How To Enter Equations Quickly In Class?
AdmiralXyz writes "I'm a university student, and I like to take notes on my (non-tablet) computer whenever possible, so it's easier to sort, categorize, and search through them later. Trouble is, I'm going into higher and higher math classes, and typing "f_X(x) = integral(-infinity, infinity, f(x,y) dy)" just isn't cutting it anymore: I need a way to get real-looking equations into my notes. I'm not particular about the details, the only requirement is that I need to keep up with the lecture, so it has to be fast, fast, fast. Straight LaTeX is way too slow, and Microsoft's Equation Editor isn't even worth mentioning. The platform is not a concern (I'm on a MacBook Pro and can run either Windows or Ubuntu in a virtual box if need be), but the less of a hit to battery life, the better. I've looked at several dedicated equation editing programs, but none of them, or their reviews, make any mention of speed. I've even thought about investing in a low-end Wacom tablet (does anyone know if there are ultra-cheap graphics tablets designed for non-artists?), but I figured I'd see if anyone at Slashdot has a better solution."
I used LyX quite a bit; the equation editor is pretty quick to work with (better than MS Equation Editor or similar addons).
LyX is generally much faster than straight LaTeX - and there's a much shallower learning curve.
Additionally, LyX works on pretty much whatever platform you want to use.

Pencil/paper and digitizing later should be fine.

There is this ancient technology called "paper" which may suit your purpose.
Once you get into higher math, you'll start using more and more symbols that require correct layout in order to display correctly. There are also these things called "graphs" and "diagrams" which are very hard to type, but rather easy to draw.
How about taking notes with pen and paper and then transcribing to your laptop later? Ok it doesn't directly answer your needs but I always found I remembered things a lot better if I took notes the old fashioned way before putting them on the computer.

Take notes by hand in these formula rich lectures, and enter them into the computer when you review your notes.
LyX
With some practice (and appropriate shortcuts), you can enter formulas faster than you can write them down with a pen.
Apparently as of Snow Leopard, the touchpad can now do handwriting recognition. So you may already have all the tools you need with your MacBook. I've never tried this particular functionality, though it sounds cool.
If you do choose to invest in a Wacom tablet, Windows 7 comes with a math input panel:

It's not very usable with a mouse, though.
Um... I didn't do it!
If you really want to get fancy you could write with erasable ink or (gasp) a pencil in case you make mistakes in your notes.
Then invest a little money in a scanner with a sheet feeder so you can digitize your notes quickly after every lecture.

Pencil and paper. I had this issue in both my math and chemistry classes. It was defiantly worth it to just do it on paper and then translate them into teX later.
"You will do foolish things, but do them with enthusiasm." - S. G. Colette
I encountered this problem too during my last year and a half in uni, so I used a low-tech solution. When I needed to put an equation in my notes, I would type "See EQ. 1-1" and fill up a piece of paper with equations. Later on (that day or the next), while reviewing my notes I would look up the eq on my sheet and type it into my notes the correct way.

The OpenOffice equation editor is just typing markup text; it's a steep learning curve, but once I got the hang of it I could keep up with any prof.

Why not use a paper notebook in class, and just enter the equations into the computer later?
If you absolutely insist on a technical solution, how about:
- using macros. Use something like OO.o's auto expand feature (whatever they call it), so that when you type exp-1 it translates to ^-1, or intl expands to integral.
- using shorthand. Find a set of shorthand layouts that work for you, then run search and replace later to make them what they're actually supposed to be. The same examples as above work -- just without the macros.
To be honest, though, you're probably best off either using pencil and paper or just improving your typing speed.

Try Latex it http://pierre.chachatelier.fr/programmation/latexit_en.php it's a great free program for making equations in latex on the mac
f_X(x) = integral(-infinity, infinity, f(x,y) dy)
Just type $$f_X(x) = \int_\infty^\infty f(x,y) dy$$ instead.
I sometimes take a digital camera (phone) picture of notes or operating hours.
I had this issue for years. Ultimately I never found anything within a factor of 5 for speed of simple pen and paper. The next best thing was LaTeX; with practice you can type that remarkably fast. (Especially if you pre-define macros relevant to whatever you're doing) The GUI-based solutions uniformly stank.
I've never found any system for digitizing handwritten equations; for a long time, my hope was that such software (preferably with LaTeX output) and a tablet would be a good solution. But the market for such things is small, and a few minutes of design work convinced me that implementing it was a lot more trouble than it would ever be worth.
Pencil and paper.
Forget the computer for mathematics classes. You will never get as fast with any sort of computer technology as you will with paper. If you want to jot down a quick calculation, or more importantly, draw a diagram, paper and pencil are painless and easy, and as a result you'll spend more time focusing on what's really important: what the professor is saying and doing on the board.
I'm a math major just graduated and taking graduate courses in mathematics currently so I've had much experience here. I've tried to take notes with a computer. I am very quick with LaTeX. You can even define your own macros specific to what the professor is likely to write and even then I think a computer for taking notes in a math course is useless.

Use a freaking pencil and paper man. It might be nice to be able to "sort" and "categorize" them for shits and giggles on the weekends but when you're taking a test I doubt you're going to be able to use a "search" system on your computer. Most professors don't require you to memorize giant formulas but they expect you to be able to recall the general uses of certain formulas from memory and be able to apply them out of context to solve larger problems. If you ever work in a mathematical field you will all also need this ability later in life, you might as well start building a "mental" search system now.
AMaya is the only one I've used. Doubt it would be fast enough for note taking though it outputs MathML so you can drop it straight in to HTML and a browser. It is open source so you can optimize it if you desire.
@de_machina
You know, I already have a touch tablet on my notebook, as many others do too. The problem is that the software is programmed to make it act as a mouse (and I also always carry a small wireless mouse with my notebook). So the ideal solution would seem to be a piece of software that lets one use this touch sensitive surface for what it really is rather than forcing it to be a mouse. Has no one written and released such software?

You're in college, so I'm sure you can figure it out...
try openoffice math. I usually do not install this program since my users do not need it, but it seems to be what you want. If you are using windows I would try the version from go-oo.org.
I hope it helps

I know you probably don't want to hear it, but Windows 7 has some nice equation recognition features for a tablet pc.
Example:
http://blogs.msdn.com/blogfiles/e7/WindowsLiveWriter/InkInputandTablet_E2A5/clip_image014_2.jpg
I use LaTeX in vim, without any scripts. It takes a bit of practicing but I don't have to wonder where my cursor gets and why it jumps whereever it wants. That's quite annoying in Lyx sometimes. It's fast and predictive, I don't even have to check the result most times. I don't even look at the screen, I actually turn it off to save battery life sometimes.
And btw, drawing graphs while the teacher is drawing them on the board can be done with TikZ faster than drawing with a pencil once you learned all those coordinate systems that TikZ provides. I've done that for about a year now, the first months were hard, though.
Anyway, I'd suggest taking notes on paper and transcribing them later. That way you learn a more from your notes and you learn to take notes that are actually useful because you have to use them at least once.
Get a Livescribe Pulse pen from Amazon or Target. The new 4GB pens are out, they hold hundreds of hours of class.
You have to use their notebook, but it records your handwriting and the lecture, keying the writing to the audio so you can review what was said with a tap of the pen or click of the mouse.
Sync to your pc or mac and you can get rid of the notebooks.
I have to say the hardware is much further along than the software, it feels more like a beta than a product, but it is worth the money. I wouldn't go to school without it.

lf(1): it's like ls(1) but sorts filenames by extension, tersely
I can think of two ways to do this.
1) In LaTeX, it's possible to make your own commands that are much shorter than the built in commands. For instance, I personally use "/RR" instead of "/mathbb{R}". This could make it a lot faster, if you repeat the same symbols often.
2) If that doesn't speed it up enough, you could use place holders that you fill in later. Type everything you can, and use say "(A)", then "(B)", and so on, in place of equations and such, which you write down on a peice of paper, properly labelled. Then go back later and enter them in. This is really just a variant of everyone who says that pen and paper is the way to go.
Well, since you're on a Mac, I'd suggest using Option-5 for infinity and option-b for integral (they don't show up when I hit preview). You can use the Keyboard Viewer to find all sorts of nifty option-? / option-shift-? combos to get you quite a few symbols.
Or, you could use pencil and paper (pen! in a math class! seriously!!!!) and your computer for other classes.
You have evaluate what this is really worth to you. You can learn just fine with notes you hand-wrote. Will all the effort you'd put into making this electronic really mean you'll learn the material in less time? And you're not seriously going to bring a Wacom tablet to class, are you? You'll look ridiculous.
If you really must, scan and OCR your (neatly) hand-written notes. You'll get enough of the words to be able to search for the concept you need later.
Or, if you don't believe me, just learn TeX markup for equations, and don't worry about getting the syntax 100% right during class. Fix syntax errors and render your notes after class.
Seriously, take a picture of the board/screen/whatever, and import the image in to your notes.
More seriously, right tool for the right job. Leave the expensive hardware at home and invest in a pad of paper and a pen.
I used this in college, albeit not while I was attending a lecture. Still, you should be able to click the various special formula buttons at least as fast as some prof is either talking through slides or writing them on a board. By the way, it is also a good tool for checking whether or not you solved an equation correctly. I've used it up to and including multivariate calculus, so it should take you quite a ways. My memory of matrix algebra is kind of fuzzy so don't remember how good it was there, but overall it should work for you.
Just wanted to add my two cents. (For what its worth, I'm a math professor.)
1. Pencil and paper + digitization
This is probably the fastest, but it does take paper and even after you digitize you may not be able to search your notes unless your handwriting is ocr compatible.
2. Tablet
I've seen a number of students take this approach. Its almost as fast as pen an paper (if not equally fast) and you dont have to scan. The nice tablets have built in character recognition so you can search your notes. On the other hand, you have to worry about battery life and whatnot.
3. Text editor
IMHO this just doesn't work. I type latex about as fast as anyone I know and I couldn't keep up with even a moderately paced lecture. I don't think picking a particular editor is going to help. It can't be that selecting \alpha from a toolbar is faster than typing it.
4. Magic
It would be really neat if there was some program out there that could scan equations (either taken from a digitized pen/paper job or a tablet) and turn them into latex. Its even possible that there is, although I've never heard of it. If so, and if it works, then this is clearly the best option, but it sounds like magic to me.

If you want really good notes, the only practical way to do it is take fast sketchy notes with pen and paper in class, then type them up the same evening while you still remember the lecture, expanding the sketchy stuff into complete sentences and explanations, equations, and so forth.
Installed linux on it: i got an Acer C112 i'm not using, battery's stuffed but the keyboard is almost brand-new, replaced it only a couple of months before getting a new one :) ... but seriously, i'm not here to sell you my old laptop, but to recommend that you look up any 2nd hand smartphone or touchscreen PDA, and use the "drawing" program, simple as that.
you can then insert the images into your notes, afterwards. pay attention _do_ try to get a linux-based one: not only do my natural instincts abhor proprietary software but you may find it inconvenient to convert from proprietary PDA / Wince image formats into something you can actually use.
of course, when you've got a "real" job you can afford $1000+ on a decent tablet PC, but then you'll not be needing to take maths notes from lecturers :)

I think I did see some lower-end tablets out there, called Bamboo or some such. I want to say I saw them for $50 - $100 US, but don't quote me on that.
livescribe.com sells the Pulse Smart Pen. It can also record the lecture while transcribing your handwriting. the best thing however, is to get last years notes, and bring it with you. then you can read along. professors usually have the same script year after year.

I know some people think pencil and paper but that is just too high tech for my blood. I'd go with a good ol' sandbox.

I've been using Wolfram Mathematica to take class notes and exams for years. By using the keyboard shortcuts you can easily keep up with the class. You can also have instant interactive graphs which will be much easier to understand than anything a professor could draw on a board, although it's not like my professors write on the board as they use Mathematica or Matlab to teach the class as well. This is at a private university in Mexico.
What's wrong with pen and paper? Why make your life so hard. You still have to write your examination answers using pen and paper right? [ unless you have an online examination ]
Firstly, the Mac has an incredibly rich simple character set. This is NOT coincidental, as Apple copied their editing capabilities from the publishing industry decades ago. E.g. in TextEdit type alt-b and you'll see a '' integral symbol (looks correct as I type it, hopefully the post wont change it). If you can learn these keyboard shortcuts (learning-curve arguments aside), you *may* be able to type these directly into your mac in class, BUT... If you take notes by hand, then transcribe them into your mac using these short cuts, or simply via the Mac's Font (e.g. TextEdit --> commant-T) and characters (e.g. via the gear drop-down in the Font) pane, you're doing yourself a much bigger favor.

Obviously pencil and paper is what everyone does, and for good reason. But if you really need your notes typeset and you don't have any time to do it after class, you should just use LaTeX. You can set up some macros for some commonly used things. You just need to be able to type fast an acurately. You said that LaTeX is too slow, but really you are just slow at typing in LaTeX. Practice and you should be able to get your speed up.
I think you've got your X and Y axis flipped. To me (and many others) a steep learning curve implies that the more you want to accomplish (x), the more time (y) you have to put into learning.

I'm a math grad student. I, and several of my fellow students do live texing. Anything else is just plain clunky, and is designed for idiots who can't handle a moderate learning curve. LaTeX is the only way any serious mathematician types up mathematics in any context.
Here is some advice on live texing from a fellow grad student:

Hello Mr. Biology Dropout, I'd like the double whopper with fries and dont fucking forget the packets of ketchup this time, you idiot.
Use a .7 mm or bigger pencil (forces you to write a little bigger which for me is also slightly faster and easier to read) on engineering paper. (one of those green ruled pads with the lines on the *back* of the page). When class is done, take your notes to the auto-feeding scanner/copier and scan them into a pdf.
That handles equations, diagrams, and regular notes. Bonus: OCR on those things is usually good enough that you might be able to search for notes if there is enough actual text. You can probably tag pages by inserting hidden text directly into the pdf somewhere, too. PDF is a programming language, so I'm sure there are comment delimiters.
At the end you'll have a complete digital record with time-stamped files organized by class (I'm assuming you drop the files into a directory for each class).
You can always typeset the important stuff for pretty-printing later, and as a bonus you won't piss off your instructor with the steady clacking of laptop keys.

emacs has an amazing TeX input system. You can type everynthing in normally, but most LaTeX magic is bound to a 2-3 key combination starting with `
I don't actually remember what everything is any more, but i did find it incredibly useful. You may also want to cook up your own bindings for things that you like. One of my favorites that everyone else seemed to hate was Cx ( would insert \left( \right) and leave the cursor before the \right).
I regularly take notes in my advanced undergraduate math classes using LaTeX. The key is to (a) use macros --- make them up on the fly and just start using them. e.g. \pd{f}{g} for \frac{\partial f}{\partial g}, for instance, or \cF for \mathcal{F}, or \sHom for \operatorname{sHom}... (b) don't compile --- compiling during class will just confuse you. Make sure you've got enough info in the .tex file for you to understand what the notes are, and then fix typos and errors afterward. To tie back to (a), actually write the definitions for your new set of macros after class.
(c) use Emacs --- if you're doing a lot of TeX you'll be happier with emacs and auctex.
(d) type faster.
If you can't go fast enough (or the lecturer is whipping through the blackboard faster than you can type), go back to paper & pencil. It's not that bad.
OOWriter has an equation editor that works by typing in command sequences like the example.

Mathematica can be pretty quick for formatting if you use the escape sequences ((escape)int(escape) gives an integral sign, for instance), and you can evaluate the things too if you're so inclined.
Of course, you'll have to pay an arm and two legs for it, but you didn't need them anyway...
I suspect you're screwed—get a pad of paper or a tablet. Any gui option is hopeless. I'm very proficient and took LaTeX notes with running equations in one course, but when I was in college, but only because it was a breeze for me; if I had to pay attention and do it I think I'd have been toast. Figures are even worse.
Sorry, but I don't think anyone's going to have a good solution here.
That's what I'd do:
During the class, insert an identifier in the document, like [a], and write the equation on 3x5 (or smaller) blank index card, using corresponding identifier. At the end of the class, take a snapshot of each of the cards and insert them into the document. If you write with a sharpie, it will be crystal clear.
vim + latex-suite
I'm as fast as the prof if he's not drawing some diagrams.
I use an IntelliPen (a better product than it's name suggests), ~$70 at Amazon.Technology is from a company called Epos, http://www.epos-ps.com
Can be used as a regular pen without a computer and STILL save the notes for use on a computer later. Useful for notes and drawings also...
LaTeX is worth learning, because the other options involve a lot of clicking as well. Mac OS X has Grapher - open the equation pallet, click what you need, then drag the resulting equation to your note document - and it's free!. MathLab is similar in this regard, but you must pay for it. Either way, it may be more work than you would like. Good Luck!
I managed through 3rd year maths with pen/paper. If you just can't handle using a pen for everything, what about just doing the slow-to-type equations on paper, giving them a number, then referencing that number in your notes. You then only need to type up the equations afterwards.
I agree MS Equation Editor is not worth mentioning, and I've never had the patience to sit down and teach myself LaTeX. I'm genuinely suprised that no one has mentioned OO.o's MATH though. Through four years of college OO.o MATH has been the best method I've found to take math notes digitally. The symbol support is reasonable (although certain weirder algebras may necessitate changing character maps), and the markup keywords are simple and intuitive enough, and configurable to boot. While it's not perfect I've definitely found that its very fast (in my case faster than writing it out by hand). I also like the fact that it integrates cleanly in OO.o Writer, which means I can inline any equations with my textual notes as well. Specifically I found it exceptionally useful in calculus, statistics, cryptography and relational algebra. Hope that helps.
I took all of my notes throughout university (including engineering courses) using OpenOffice.org. The equation editor in OpenOffice is easy-to-learn, fast (as in, no mouse use required and the keystrokes are all sane), and the completed equations look great. (By default, there isn't a keyboard shortcut for inserting a new equation, so you'll need to manually assign one—I used Ctrl-Shift-F, if I remember correctly.
Your example would almost work as is; it would be entered as:
f_x (x) = int from -infinity to infinity f (x, y) dy
Or, if you prefer your parentheses to stretch (in case you have fractions inside, or what have you):
f_x left ( x right ) = int from -infinity to infinity f left ( x, y right ) dy
Either way, it comes out looking very nice. The one thing that takes some getting used to is that you need to make liberal use of whitespace (e.g. between f and the opening parenthesis of the function), otherwise things will occasionally come out looking a little strange. The best part is, when you don't know what you need to type for a particular symbol, you can select it from the menu and OO will insert the plaintext code, which makes it very easy to learn the code for new items.

I was disabled and taking notes was VERY slow for me if I tried writing. I used a word processor WP or MS Word (I don't remember which one) to take notes. I had a similar problem until I discovered that I could map an entire phrase into a single keystroke. For example: "ALT + CTRL + F " could be "f(X) = " You could even be more elaborate because certain phrases are used time and time again in lectures. My longest remapping was 20 characters. For different classes, I had completely different keystroke mappings. Just be careful not to remap the standard keystrokes.
This technique worked for me all though grad school. I also used a tape recorder (get the professors permission first) and reviewed my notes after class to make sure I got it all.
Seriously. Whip out the digicam and take a picture of the blackboard/whiteboard/projector screen. I was in a class once where a student did that and mailed the pictures out to the entire class every night. The professor loved it.
I used TeXmacs (on Linux) to take notes in all of my classes, and it was great for all of my subjects. My math notes were perfect, and I could convert them to PDF for emailing to classmates, but the only downside was that I never worked out how to input graphs (I could never sketch them in handwritten notes, anyway).
With Vim's editing capability, the shortcuts defined in VIM-LaTeX let me take notes as fast as my professor types them.
I had but a simple dream, to destroy all humans.
In one of my University lectures the problem was solved by some guy by setting up a Wiki that could handle latex. This was used by multiple people to create a quite useful script from hand written notes. So while this doesnt answer your question, its a solution to your basic problem: putting less work into creating a bunch of pdf containing the lecturs content. The Wiki expanded quite a bit btw, now covering multiple lectures. If you care to have a look: http://mitschriebwiki.nomeata.de/ but be warned its in german.
This is what I was going to recommend! I picked up a cheap and outdated Wacom tablet from E-bay, and use OneNote to store all my notes in. It's a thing of illegible beauty!
Can't go wrong with the new equation editor in OneNote 2010. Beta will be out in two weeks. It will work for a year. The new version of OneNote is great, I've been using it since May.
"f_X(x) = integral(-infinity, infinity, f(x,y) dy)"
Why not type it fXy=intgrl -inf,inf,fx,ydy... omit a lot of your structure and unnecessary letters and typing equations becomes much quicker. If you're actually going back and looking at them later you can fill it out a bit with parentheses where appropriate, etc.
"Growing old is inevitable; growing up is optional."
I had a couple of favorite math professors. Here's what they did that made them so much better than the rest.
They used transparent overheads and scanned them for us at the end of class. The greatest thing about them was that there was no erasing in the middle of the lecture... they wrote in dry erase but rarely erased anything of value... instead they would just swap them.
If you can convince your prof's to give it a try... even if you must offer to digitize them and post them for the teacher... its by far the best system I know. This process kept everyones eyes on the lecture instead of down in their notes. I would take notes occasionally, but only procedural things that weren't written on the overhead.
Sometimes the best solution is to stop wasting time looking for an easy solution.
Hi there, I faced the same problem back in 2004 when I was taking a preparatory Maths class for the the EPFL in switzerland. The way I managed to solve the problem was by using two amazing features of the Mac OS operating system, the character palette and key binding. I set up my system so that when I was typing in word or pages or whatever else, I could use letter keys with symbols to give me access to the most common symbols. Once I had the 24 most current ones mapped to the letters with modifier keys I could then also use the autoreplace system to use short key codes and replace them with the desired symbols. The only difficulty is that I ended up writing a lot of brackets to deal with fractions. I hope that this helps.

It's not only great for doing engineering/physics homework, you can type a pretty equation really quick if you learn the keyboard syntax. It's actually pretty awesome, although i'm rather upset that a) it seems that it has disappeared from most engineering curricula, and b) PTC hasn't released a new version in at least two years. The ASME chapter at the university I work for sells student licenses for $30 instead of the regular $119 from the bookstore.
Scientific notebook is great, not only is it easy to input the equations but you can solve and graph them in there as well. And you have your familiar LaTeX based format too.
I took notes for a 2-term course in differential geometry using LaTeX, it worked fine. I drew pictures in XFig. I actually paid for my laptop by selling the notes back to the instructor after the class was done!
Basically I used ZERO technology; every time I tried to use something clever it just slowed me down. My main tricks were
1) use a syntax-highlighting editor
2) make sure the document always compiles
3) write a couple perl or python scripts to do slow things (like entering matrices or commutative diagrams)
4) try not to use too many macros. Just learn the names of all the symbols.
Your example,
f_X(x) = \int_{-\infty}^{\infty} f(x,y) \;dy
really only takes a couple seconds to type if you don't hesitate. You can catch up on any lost time when the instructor is writing sentences.
I took notes on my laptop extensively all through my undergraduate degree in Computer Science, and I always used OpenOffice.org Writer's equation editor. It has a nice, concise syntax, and it was, in fact, possible to enter even very complex mathematical expressions in real time, faster than my prof was able to write them on the board. This was true even for matrixes.
Here's an example of some of my notes made with OO.o: http://csus.cs.mcgill.ca/wiki/COMP-330_(Panangaden%2C_Fall_06)_Lectures
My linear algebra notes would be more impressive, because they often involved fairly large and complex matrix equations, but I never made those notes available online.
I had a colleague who also took notes in class who had quite a nice method - he wrote all of his notes in wiki markup, with latex for the mathematical expressions. He didn't have a laptop, but instead used a PDA and small, foldable keyboard.
An example of his notes are here: http://csus.cs.mcgill.ca/wiki/COMP-302_(Panangaden%2C_Pientka%2C_Winter_06)_Lectures
I think it's quite a nice result.
Off topic to this discussion in general, but maybe useful. Heres my solution, constantly using VirtualBox took me from 7 hours to 2 hours battery life, these get my back to about 6, give or take screen brightness.
First, buy CoolBook
Buy CoolBook from coolbook.se. The trial doesn't do anything actually useful, its more of a 'will the app run' trial than anything else so don't try it and throw it out cause it doesn't work. Its only $10, and after you register it will takes some time (few hours) for them to email you the 'key'. The 'key' is generally your First and Last names and the email address tied to your paypal or google checkout account. Once you've paid, you can use it very shortly after, well before the email arrives in my experience.
Set it to limit your CPU temp as much possible, unless you're playing WoW you probably won't notice the difference, this will keep your mhz and cpu speed down. I used it to lower my voltages slightly as well cause the thing gets way too damn hot sitting on my lap, you probably really don't need that though. I only use lower voltages for the bottom end of the CPU speeds, I leave the higher speeds as default for stability. I haven't tweaked this much as the temp limiter does most everything I need.
Second, disable 3d accel in virtual box if its enabled, this will help a lot if you use Vista or Win7, at the cost of 'ooooh shiny'. If you have multiple cores, only use one. That'll help keep things snappy on your mac without pushing up the speed of your CPU since it leaves a core for the host OS untouched. Not as big of an improvement as disabling 3d accel though.
Third, in the Energy Saver preference pane, set your graphics to 'Better Battery Life' if you have the option for your card. This gave me a good bit of battery life and drastically lowered the heat level. To be honest I have no clue what it did as far as performance, I haven't noticed, I switch it back if I'm going to play a game that needs it.
Forth, lower your keyboard backlighting (if you have it) and display backlighting. Depending on your system this may not be as useful, I have one of the LED backlighting machines so its not as big of a difference as FL, but its still 30 minutes to an hour of extra time on a full charge. If you have the preference option to have it track external light sources, you'll automatically save power when the lights are lowered and eyes too, but it seems to vary too much like when I move around in front of it and block a light source behind me. Makes you think you're going nuts when the screen dims and brightens seemingly randomly so you may not like the feature. It can certainly be annoying in the wrong environment, a typical lecture hall should be fine.
At the end of this, I'm almost back to full life on the battery, I just fire up my virtual machine now and forget them, but you HAVE to make sure you don't have any background processes running on them that eat CPU. Things like Google Desktop Search or the Windows Search 4.0 will bite you when you least expect it, they always seem to start indexing when I'm the furthest away from a power source, and I don't notice them until I wonder why my battery meter is dropping from several hours to a few or even minutes, which means its already consumed a fair amount of your reserves. This is one place things like Parallels have an advantage. Spotlight can index my VM drives and is far more aware that I'm active than the VM is.
Your milage may very, I've done no real testing to prove out these differences, its purely anecdotal, but, its something and may help you use your Linux or Windows VM through a days worth of classes.

The pulse smart pen is far better. I tried the Wacom bluetooth tablet but the problem is that you cannot see what you write. If you use the Pulse Smartpen then it acts like a real pen - so you can see exactly what you have written - and as well as recording exactly what you wrote it records audio as well so you end up with a document that you can click on to hear what was being said at the time that you wrote that bit of text.
The only downside is that it needs special paper which you can buy in notebook form or which you can print yourself using a laser printer. The windows version has some extra software you can buy to perform OCR on your handwriting but since I have a Mac I have no idea how good it is. There is even an open SDK for you to develop your own applications for it but it unfortunately only supports Java.
Open Office ships with a pretty nice little eqn editor, mostly based of TeX, but the updates are real-time.
For liberal arts (or anything strongly language based, like law) typing your notes in class is fine.
But law is the exception for technical subjects. For most others, you need a pen and paper. There are simply too many symbols which take too long to type into a qwerty keyboard, or there are too many diagrams.
I have terrible handwriting and used a pen and paper throughout engineering school, and my girlfriend is doing the exact same thing in medical school now.
Use the right tool for the job.
Seriously if taking notes worked that good on a computer classrooms would be full of them all the time. Computers are for after class when you need to get work done faster, thats what it was designed for. I thought I'd take notes on my netbook too a while back when I got it, but it just didn't work... now its retired to a bedtime email checker lol.
"They confiscated everything, even the stuff we didn't steal!"
There's this magical invention called a "pencil" that goes well with another magical invention called a "notebook". Combined, the two will let you keep up with the lecturer. If, later on, you have the overpowering need to be 1337, you can transcribe the notes at your own pace into your computer.
Your word processor should be able to auto-replace specified strings. Not sure if/how you could enter the symbol for infinity, but I'm pretty sure greek is available. And "inf" isn't a killer to input anyway.

Many people never bother to check out the built-in "Calculator" app in OSX
click the VIEW menu for options like "paper tape" and you can use the scientific calculator part and record everything and then print it out or save it as a text file.
but I really like the previous suggestions for handwriting it out for now on paper...
I like microcars
I've never used it, but Pogo Sketch seems to be what you're looking for. (For those who don't want to click the link, it's a stylus that works with trackpads. You can use it with any app that lets you draw with a mouse.)
If you could make it work with Evernote that would be about ideal.
I don't understand the purpose of the thousand posts saying, "Just use pencil and paper!". That's my preferred approach, but why reply if you aren't going to answer the question? You don't really think that an advanced Math student never thought of using a notebook, do you?!

Microsoft's Equation Editor isn't even worth mentioning
Why the equation editor is not even worth mentioning? The one comes with Office 2007 is pretty good. Some of my friends are more likely to use Word instead of exclusively Latex because of it.
Seriously, a decent phone camera even. Just get Evernote (differences between premium and free are listed on that page) and take notes by hand then upload them that way. It's even (rather) searchable if your pendmenship is somewhat legible. Just a thought.

This is not the old Equation Editor 3.0 from Word 2003, which is a crippled version of MathType, but rather a brand new equation facility in Word 2007, which is also the basis for the new equation support in the OneNote 2010 beta another poster has referred to.
The Word 2007 equation editor supports a "linear format" for completely keyboard-based input, which is based on TeX-like commands like "\sum" and "\int" and is documented in this Unicode technical note: Unicode Nearly Plain-Text Encoding of Mathematics
I've been using this for my math classes since last semester, with great success. Once you master the linear format, it's not difficult to keep up if you have a reasonable typing rate to begin with.
OpenOffice.org Writer + Math. When you insert a formula into a normal document (Insert->Object->Formula), it brings up the OOo version of an equation editor, which seems easier to use than some others. You can type "f_X(x) = int from -infinity to infinity f(x, y) dy" and it is displayed as a math equation. So you end up typing out the equation partially in words, like you have been doing, but you get normal looking equations in your notes. And since you are just typing (no mouse, tablet, etc.), it should be fairly fast.
You already have a textbook for most of your classes. Either take paper-written notes and turn it into LaTeX at home, or find a way to record the lecture (ideal) and just pay attention. I would just pay attention mostly, and then perhaps browse the MIT Open Courseware for recordings of similar classes. What you do not want to do is try to type your eqns very fast - you will screw up. Speed is not to your advantage here. Also, there is this supposedly amazing pen / recording device on the market. Get yourself one of those too ... Taking notes almost never helped me, other than by keeping me awake during class.
[This is a non-answer to your question. But it's a good non-answer if my success and student and teacher is any measure.]
Don't take notes in class. Seriously. I've forbidden note taking in some of my classes. I hand out copies of material not in the book. But when I lecture, I do so with the intention that what I say be listened and paid attention to. If someone's trying to write what I say, their attention and working memory is so divided that they can't be picking up much of anything.
This is especially true for maths. Of what purpose is it for you to have to watch someone write out equations? Of what purpose to write them down at the same time? Is the content of so little importance that they can waste their time and yours with speed writing exercises? The writing/rewriting is important for memory. That being so, why tax the memory with the process, reducing the result?
Ask your instructors for copies of their class notes. Explain why. If they feel it's somehow cheating, ask to record their lecture. If they're not saying the equations out loud, record in video. Then whether paper copies, audio or video, transcribe. More than once if need be. Work with them on this. It'll be to everyone's benefit. If they can't believe that, prove it by recording a class with them writing stuff as usual and people copying, and calculate how much more time it takes for them to write, you to write, you to ask what that wiggly thing is, them to tell you, them to write, them to ask if everyone is caught up, on and on; vs. hand out a paper copy, them lecture, you listen (and add just tiny clarifications if necessary on their notes).
I really am serious about this, and pushing this agenda has made me a favorite of students (who get better grades; I've tracked that too) but gotten me all kids of grief from other instructors. They see the process as one of confrontation, forcing students to do things a certain way and any other is 'cheating', or could be used for cheating, and frankly very little rational explanations are forthcoming. I picked it up from instructors who were more concerned their students learn than jump through hoops like speed writing as the sole means to collect material covered in class. I hated hoops as a student and refused to use them as a teacher. Instructors that can't get away from hoops are using them as a crutch. Help them learn to do better.

I once took a class in AI in which the professor showed us a film from the late 1960's that demonstrated just such a tool. You wrote an equation in math notation with a light-pen (or something similar) on to a screen, and it translated your marks (pen movements) into an internal representation and then displayed a formatted version on the screen. (Professor Blackwell, I think was his name, and he worked on part of that project before teaching.)
If it could be done for a research project in the late 60's, then surely it's still technically possible and could probably do better. It's amazing that much of the UI technology we take for granted now existed in the 60's (as expensive research projects). Graphical GUI's, dragging, mice, light-pens, stroke character recognition, etc. Sutherland's great work included. Much of it was funded by the military for use in radar analysis, interactive flight planning, etc. Xerox extended these by using the overlapping paper metaphor in the 70's.

It's possible the author is taking more advanced math than I did (although I would be able to handle the equation in question), and/or is a slower typist, but I was able to handle equations like that along with matrices when taking notes. It was tough at first but after a few weeks I was moving along pretty quick and was only a hair slower than the analog folks.
There were only 2 real problems I found.
1) When a new topic came up I'd have to do a quick google to find how to make the relevant terms.
2) I never found a good solution to draw and integrate diagrams quickly enough.
For 2 maybe there's a fancy latex editor or maybe just practice (I didn't have much latex image experience at that point). But overall I found that the value of having nice notes outweighed the two negatives.
So it is highly course dependent whether LaTeX is viable. But depending how many LaTeX notes the poster has taken there is a possibility they simply haven't had quite enough practice and will be fine if they stick with it.
I stole this Sig
I used to take notes electronically all the time and I ran into your problem in different classes. What I realised though, was that it was not a matter of speed, it was a matter of categorizing! Allow me to explain. You said you wish to take notes so you can sort them later and what not, that's a great idea and it worked great for me too! What I did for my equations though, was write them by hand on a notebook and (in the notes) refer to them as EQ1, EQ2, EQ3 etc... When I got home, I would review my notes and I would then type the equations in the notes! This proved to be sufficiently fast if you have a notepad that you can fit on the desk with you (if you have a full-sized laptop, maybe try a smaller notebook). I ran into this problem when I took a CS class that was making use of flow charts, I certainly didn't want to draw the damned things with a tablet, I simply drew them by hand, referred them in the notes as fig1, fig2 etc, and when I got home I would (sometimes) scan the drawings and paste them in! I know this isn't a suggestion for software, but maybe it can help you with your notes in the mean time.
A black cat crossing your path signifies that the animal is going somewhere. -- Groucho Marx
Most of you who are recommending plain paper are missing a very important point: The ability to search through digital data (in stark contrast to analog).
Pen and Paper is fine in multiple categories: cheap, easy, your free to do whatever you want. (And it has this nice, satisfying feature that you can rip it to pieces and smash it against a wall without destroying expensive and fancy techology) Worked fine for me till now (I, myself, study mathematics)
But it has one very major flaw: You can't just type CTRL+F on your trusty college book. Which would be kind of a dealbreaker if there were ANY alternative which could match it in adaptability. My professors tend to write some quite fancy symbols once in a while, I just can't imagine how any handwriting-recognition-software could handle this. So it's paper for now. But I'm sure I could save many workhours if I could easily search through my writings in a digital fashion...
Some very geeky students manage to type along with LaTeX, one of them uses an 7" netbook and I admire him deeply for it... and I even know one who does it in MSWORD (he has memorized most of the ASCII-Codes for certain symbols... admiration is somewhat lesser in this case...), but they hardly keep up.

you'll have recreated the fabulous 2-buck pen-and-paper experience. Go you!
The question I don't understand is WHY. The quoted statement outline the end result pretty clearly. I understand slashdot loves to use fancy technology to solve simple problems, but sometimes simpler is better. I already have a HUGE set of properly formatted equations all nicely written out, it's called the Book.
Note taking, for me, was to summarize what the teacher said, in MY words so that I could understand it later. I just learn by writing it down, there were some classes that I never kept the notes. I'd grab what ever scratch paper was by the printers, write on it, and toss it after class. (Statics. F=0, how hard is it?). I still have quite a few of both textbooks AND notes for a class. I have the hard equations and then I have how I learned it. Heaven forbid ever become an engineer, where the teacher is drawing simply supported beams on the board, the teacher is drawing feedback control systems.
Anything worth writing is worth writing once. If someone already wrote it in the text book. Then that is good enough for me. In some classes we'd photocopy the problems out of the book, cut them out and paste them on the homework. It was better looking than my drawing and clearer than my handwriting... and I can guarantee I never made any transcribing errors.
Instantly digitized notes seem like they'd be great for classes where the content will never exist again outside of that class. Philosophy debates, taking notes as a reporter, etc. You're going to spend more of your time trying to figure out how to make that '2' go subscript of that '4' in the numerator with the summation block than you will learning the content. Put down the computer. Grab a good mechanical pencil and a $.50 notebook from walmart and quit worrying about it.
If you HAVE to have a digital copy. Take notes on something that can easily be separated into individual sheets (3 ring binder and 8x11s with 3 holes). When the semester is over take it to any decent multifunction machine, put it in the top and let it scan everything for you.
Monoprice has tablets starting at around $17. I have the $36 8" x 6" one and it works as well as the $200+ Wacom tablets in my experience. http://www.monoprice.com/products/subdepartment.asp?c_id=108&cp_id=10841
It saves tons of time. The entry of equations is fast and you don't even have to finish the derivations yourself, just hit Shift+Enter and there's the result. The only real trick is trying to get the prof to let you take your "notes" into an exam...that and the price tag.
Seriously though, I'm going to throw my vote behind the pencil/paper method. If you want, digitize later, but pencil/paper gives you necessary flexibility. You need to be able to work through derivations as you go, follow along. Keeping up isn't enough, you have to follow the logic of the lecture and having room to do scratch work on the side, full and easy control over the layout (which is important to how you organize ideas) and the ability to see what you're writing down is all critical.
If you insist on digital input is has got to be a WYSIWYG editor (not that I have one to suggest). LaTeX is irreplaceable for writing a thesis but you'll never follow the logic of what you're writing if you're looking at source code. Transcribing what the prof writes just doesn't cut it for advanced math, you have to follow along and I argue that that means using a pencil.
So if this is the future...where's my jet pack?
Office Vista has a nice Equation editor. I few clicks and you can enter Equation.

$200 and never miss anything, brouhgt one after i saw it at conference and have nevre looked back wish they existed when i was a student.
There's also /Applications/Utilities/Grapher.app which, with a bit of practice, may be suited to the problem.
It's a complete waste of time. Notes are useless after the course is done. I kept mine for 10 years after I graduated, then tossed them. Textbooks are of some use. Cheat sheet were the most useful. If you MUST write notes digitally, the just put a number for the equation. Then write the equation down on a piece of paper, and type it out later. Or have some generic equations pre-written in another file, crtl+c, crtl+v. Honestly, in 10 years or less you will find that all your typing was a complete waste of time.
doesn't google docs have a good equation editor?
http://googlesystem.blogspot.com/2009/09/google-docs-has-equation-editor.html
I'm actually more in favor of pen and paper myself, but each methods has advantages and limitations and it has already been discussed here.
If you must use a computer, then I think using paint or an equivalent simple drawing program to draw equations is a pretty good suggestion! It is really fast and has no learning curve at all, although there is a question in my mind about the readability of your drawing -- but that improves with practice. I also don't think you could do it without a mouse-like device.
Keep both your word processor and the drawing app open so you can switch between them. Give each equation a number when you draw it, then reference the number in your notes. Use some standard naming convention to relate the files .. e.g. chem101-lecture-2009-10-25.odt and chem101-lecture-2009-10-25.drw (or whatever the program uses for file extensions).
I found that the WYSIWYG editor + keyboard shortcuts for MathType was fast enough for me to keep pace in a lecture.
http://www.dessci.com/en/products/mathtype/
P.S. The free trial version contains enough features for most lectures / note taking.
The equation editor in WordPerfect (any version since way back about 5.1 for DOS) lets you enter equations as nice simple text and does a remarkable job of formatting them correctly for you (I used to use it ALL the time), but it probably isn't "fast" enough to enter them on-the-fly like you want.... Probably best to enter them graphically into your favorite program (perhaps with a stylus in this case) and then clean them up later if you like. I've seen several programs over the years that let you use a regular laptop touchpad as a small tablet, but can't recall any specific names off the top of my head. Used to even be built into some of the early touchpad drivers... I'm sure google would be your friend on that one...
So, this is just my experience, and I'm sure you won't listen or will have a different experience, but:
I tried taking electronic notes in maybe a half dozen undergrad math classes using a Newton message pad in ink mode. I believe that I did significantly more poorly in those classes than if I would have used pen and paper. It was just too futzy. The Newton worked fine, because it wasn't trying to recognize, but the added layer of technology didn't justify itself in terms of the potential but unrealized benefits of search- or store-ability.
I did homework assignments in LaTeX and got quite fast in it, but not fast enough to take notes with it using a keyboard. (Although I sometimes felt like I got points off because my work was too easy to read!) The classes I did best in I took pen and paper notes and then later transcribed and condensed these into LaTeX study guides.
On the flip side, for less notation-focused classes, like say, literature, it was awesome to be able to search my electronic notes and I think this justified the effort in changing my handwriting so the Newton would read it. I still see the effects of this in my writing today!
Good luck!

Hi, I'm a physics professor. I say, take your notes on paper. Math is the most computer-incompatible writing system ever designed. You'll never ever be able to type equations fast enough to keep up with me on the blackboard.
And even if you manage to find a math entry system that's fast enough, it won't help you with the diagrams, graphs, and sketches.
Of course, I don't practice what I preach: my own lecture notes are in text files. But that's because to me, "block ramp friction mu=0.2, 1 kg 30deg 1m long, find final v. U=4.9 Wf=1.7 v=2.5" is a complete set of notes for a 20-minute segment of lecture.
Oh, also: write in pencil. I guarantee you that whenever you bring a pen, I will spend the entire lecture correcting minor mistakes by erasing with the heel of my hand, changing variable notations, and editing diagrams and drawings halfway through working a problem.
Used to work there. Honestly, you can't beat it for mathematics editing, graphing, etc. Saves in Latex if you want. Free trial downloads too if you want to give the tires a kick.

Not clear to most posters why he's already assumed the keyboard bit.
Take a photo of the equation on the black or white board, and on your computer, invoke the command that puts a timestamp in the file. Later, at your leisure, you can pull up the timestamps, and match them to the photo timestamps, and transcribe the equations.
I've been using Wacom tablets for lecture and research notes for four years now. At first it's quite hard to use a pen tablet as opposed to a tablet computer, since nothing appears under your stylus, and you have to write while watching the screen instead of your hand. But I got quite used to it within a week. Adjusting the scaling between the tablet and the screen may be important — an 8" tablet worked badly when I tried to map it to my entire 23" screen, but mapping it to about half the screen worked fine.
For portability and for study advantage you might well be better to transcribe paper notes, but you might still want to do the transcribing with a tablet and handwriting instead of TeX or text. For giving lectures and for research calculations, I find two great advantages of electronic notes over paper: they're instantly searchable (not the scribbles, but typed text); and I can fix up my equations by drag and drop, copy and paste. The speed-up for making nice, neat notes this way, instead of on paper, is comparable to going from typewriter to word processor to produce a fair copy. My handwriting is not as elegant as typeset equations, but it's enormously faster to draw integrals and fractions and so on than type out TeX.
As a program to handle the tablet input on a Mac, I use Curio. Curio lets you drop in pictures and figures and typed text, adjust the page size arbitrarily, and a bunch of other stuff as well.
- I hate writing, and always have and avoid it wherever possible - it hurts my hand and my handwriting is awful.
- I was using computers way before anyone else in my school, I even took some of the lessons that I was supposed to be taught in (the teacher found it easier that way).
- I went to university to study Mathematics and Computing and had already had five years (at least) of proper exposure to things like Maple, Matlab, etc. (I was doing my A-level projects in Maple when nobody else, including my teachers, had even heard of it) through my brother who attended the same university.
Every single mathematics-based lecture, for three entire years, I hand-wrote notes. It's the only sensible way to do so. There isn't a notation or shorthand that can cope with rapidly sketching down formulae (especially integrals, sums of series, etc.) and diagrams. In some subjects, a simple diagram showing an angle, or a particular piece of geometry is invaluable and could takes hours to reproduce properly on a computer. I know, because for the last ten years, I've worked for tuition centres, state and private schools and I'm often asked to professionally produce an electronic version of their course materials (99% of the time mathematics because that's my speciality).
Don't waste your time, memory, money and brainpower - just take pad and pen, or use a touchscreen/tablet PC if you *insist* on using a computer. When you're taking notes the last thing you want to be doing is taking down the mathematics like it's some kind of gospel. There will be a million books on the subject where you can find the nuts and bolts of the process, but if you lose that "feel" of the mathematics that you can only get by watching someone apply it in front of your eyes, you'll never truly understand it.
The point of a lecture is to demonstrate and explain and give opportunity for questions (yes, ask questions... why does *nobody* ask questions in lectures? It isn't forbidden, just don't waste everyone's time with trivialities!), you learn more in a ten minute lecture on a particular subject than you ever will by studying the materials from that lecture. *Being* there, with the enthusiastic tutor, and the commentary they give, is what makes the mathematics explain itself. Everything else is just paper-based memoranda of that lecture. Someone, somewhere will be selling notes from that lecture. I've taken copies of complete stranger's notes (with their permission) when I missed lectures for reasons beyond my control. Notes are memory-aids only. Wasting an immense amount of time recording them in such a fashion is to focus on the aesthetics of the tool, not the job you're doing with that tool. All you're actually doing is writing the book that your lecturer learned from, you're not learning anything, and doing so at great expense. Your concentration should be on the mathematics happening in front of you, not the paper in your hand or the computer under your fingers.
I often just sat in awe when I was in a lecture and watched the mathematics unfold in front of me, sketching only notes on the specifics.
Scribble notes. If you have special needs, ask to video/record the lectures or for the lecturers to provide assistance afterwards (and complain to the highest authorities if they don't let you). Then, study, study, study from your notes, your memory, your skills, and the vast wealth of materials on every subject imaginable. Anyone can find out how to apply equation X to input Y, or read a book on graph theory or calculus, but advanced mathematics is more about the patterns and the art of being able to discover, use and apply that knowledge, not copy from rote from two-year-old notes.
I graduated. Not a great grade but I was hitting a wall in my abilities in even the first year, a wall I've never been able to pass in the years since. Some courses ran like water through my sieve of a brain, and some were just second nature (and still are). But at no point did the actual taking of my notes interfere with
Have you tried Wolfram's Mathematica?
Not only it helped me take the required notes on every math related course but also helped solving/confirming many problems.
Not really saying if its cheap or overhead... just saying that it worked for me.
Cheers.
At the time I used straight LaTeX, but I made it work. The trick was to get a good editor and set up keyboard shortcuts for common things to blaze through the process quicker. Add on top of that a bunch of renaming functions in the preamble to save keystrokes for other common actions and keeping up isn't much of a problem.
That being said, I'm going to cast my vote for Lyx because you can still do all I suggested above, but it greatly aids in building tables, matrices, and other things that'll slow you down a bit. And don't be afraid to use shorthand that won't format properly when necessary, as long as you know what it says you can always fix it after class or during a lull in the lecture; I find this typically takes less than 5 min. And use lots of white space. And reconsider what the best way to keep notes is; when you have a medium with the flexibility of files, folders, etc, I find it's usually better to take notes by topic instead of chronology of when it is said.
Funny story, took notes all semester for my stat class that way and we got to use 1 page of notes for the final. About 20-30 minutes of copy/paste-ing gave me every equation we used, qualitative descriptions of what they do and when to use them, and a whole host of other useful stuff. Never studied beyond doing my homework (which I only did most of the time) but I got a 297 out of 300, highest grade in a class of ~150 and about half a standard deviation above the next highest score...
You could write a little script that lets you write LaTeX equations but leave out the backslashes. I don't think you're going to get anything much faster than that for computer input.
You could write them down on paper and then scan them or typeset them later...
Have you considered LiveScribe?
Those notebooks just aren't practical to use on your lap: the numeric keypad might be nice, but it means the main keyboard and trackpad are off-centre to the left. Also, an 80x120 tablet is too small to be usable for writing - it might be OK for a bit of photo retouching, but not much else.
Stuff That DOESN'T Matter.
I'll write it again: What a stupid FUCKING question.
What's next on Slashdot: How to Do I Keep My Drink Cold While Working On Homework?: Refrigeration With Cryogenics: Liquid Hydrogen, Liguid Nitrogen? No, absolutely NOT. Use Liquid OXYGEN.
How Do I Maintain Alertness During The Day In College Classes?: Please schedule an appointment with a neurologist to see if you have narcolepsy! Please visit a nutritionist to see if your diet is deficicient ! Absolutely NOT! Use METHAMPHETAMINES. They work .
How Do I Graduate From University With Grades HIgher Than C?: Do your fucking HOMEWORK, moron.
Thanks in advance,

Easy. Get Maple
Then write code to do your homework, at least that's what I and every other respectable geek did in higher level math classes.
It comes with graphing calculator. which would seem to be tailor made for what you're trying to do...
-- it's ridiculous how many people misspell ridiculous... (damn, damn, damn...)
I have run into this problem and managed to overcome it. Just use Microsoft Equation using shortcut keys. You can insert a new equation, almost any mathematical expression and save equation using only your keyboard and it gets really fast, almost like pen + paper. If you need more functionality, you can use MathType, it will definitely cover all your needs.
Holy crap, is that bit of software still going? I remember seeing that back when I was an undergrad (>10 years ago now) and it was well-established even then. Never used it but "Scientific Word" had a bit of a reputation among some of my older peers.
It's quite easy to use, comes with your laptop and provides good copy and paste between the equations that you are entering and other applications. The downside is that the library of functions isn't that complete since it's orientated towards actually producing graphs. As with everything, I guess it depends on what you are doing...
It can be found in /Applications/Utilities/Grapher.app.
Just point a webcam at the lecture's overhead board and take a photo...
You can tie it into the notes, and add it using an equation editor later on.

I used Infty Editor in my classes - I think it's based on LaTeX but, it was pretty quick. I didn't use it to take notes in realtime though, so I can't tell you how successful that would be. http://www.inftyproject.org/en/software.html
I used mathcad in college for the classes that were not too heavy on the equations.
For classes like physics and process control it worked fine.
And on the subject of having to find symbols that someone mentioned you can just write out a word to define it as a new variable.
I had equations after classes that contained stuff like "osquiggle^pHat = 193.7" which worked fine ;)
Costs a bit though, but was well worth it as I could use it to plot stuff efficiently. While my fellow students would labor to draw 3d graphs on paper using colored pens for turn-ins I would just plot em in mathcad ^.^
Yup, second OneNote.
:D
If you can find an edition of OneNote 2010 (Technical Preview, currently), it's even better. OneNote 2010 has equation editing similar to that of Word 2007, which, if you've actually used, you'd realize has all sorts of Latex-like features, just that it's transcribed on the fly.
You can type
\int_-\infty^\infty 5xdx
or whatever, just the same way. Matrices are a bit different, but very much possible;
\matrix(1&0@0&1)
Creates a 2x2 identity matrix.
That said, don't pirate software.
TextMate is a great text editor and it has a pretty sophisticated templating & tab-trigger system. You could define your own tab-triggers to produce templates that you fill in with the equations. The bonus here is that you can define your own.
I use the templating system for writing code, but the same concepts would apply to using it for equations.
Seconded. Although at the time I was in college, I ran Linux, and couldn't use Scientific Notebook. So I just learned LaTeX instead. Got damn fast at it, too, copying notes in real-time. But my experiences with Scientific Notebook were absolutely enjoyable.
No comment.
I've recently returned to university, using an amd64 netbook (with a better display than most and more full-size keyboard--running sidux64, like all mine) and just this bamboo pen pad. 31yrs ago, when I started in physics, I wrote only with a fountain pen on quad pads. It's still by far the best way. But I'll use a small camera, the pad, and digitize those outrageously-priced texts with the camera stand I built. And I'll combine all of the aboves.
I do recall some annoyance at one particular prof from back in the day. She used 8 colors of chalk for her drawings on board. Very annoying to not replicate in notes. Even tried the three-color-ink pens, but that was far too much trouble, and never could compete with a proper fountain. (She was like everyone's grandmother, so no one complained.) Later, I took to cleaning the boards with the real sponge/bucket included in every room in our department, mostly to make them easier to read, with my poor eyesight. That became an anonymous tradition, before slashdot!
I also started the "tradition" of giving complete solution sets (with all steps written) to all the students, so they'd each have a fully-worked set before the exams. Cost me a ton of money, but my kids were the tops there. And they didn't have to scramble to make their own poor notes. They could listen and learn, or so I hoped. Oh, and a set of my notes sat on the corner of my desk, in case they tried to find me and couldn't. The honor system worked to keep them there, except for one student, who swiped them without replacement. Found him years later--as a dentist. Scares me to this day.
Like in the old days... by hand with a pen and a sheet of paper.
You can't use the standard keyboard which requires you to reach over to the shift key to access mathematical symbols and has the numbers way at the top. You need a numpad in the center (789 UIO JKL M works well) and keys around that mapped directly to things like + * and (. Screw the exponent symbol - numbers at the front multiply, numbers at the back, eg. 24(x+2)3 = 24 * (x+2) ^ 3. Map every key you can find to some mathematical symbol (you might want a specialized font). This will give you the fastest you can get without special software.
I've actually typeset maths (vector spaces, probability etc etc) in LaTex directly in lectures directly. At the end of the lecture a nice pdf ready was ready for printing. How?
I had a infra-red keyboard and Palm Zire 72 with a wifi card. I simply ssh-ed into uni servers and used vim with vim-latex. With a .vimrc, all sort of defined abbreviations allowed me to generate the LaTex markup quickly. For example: .sc -> \subsection{ .ssc -> \subsubsection{ .* -> \times ./ -> \frac{
At the end I just hit the \ll to compile. Worked like a charm on far less powerful hardware than you mentioned. However, you do need to define your own abbreviations and know LaTex well. If you are an emacs user, you could also try emacs -nw
Just the solution I used - a fancy GUI frontend may be faster than typing the full markup out but not as fast as defining your own keyboard abbreviations.
Can you please just show the mathematical equation for this curve of which you speak? That way we won't have to use imprecise words.
This issue is a bit more complicated than you think.
Wacom's Bamboo on windows having a Mac?... Leopard has a fantastic support for tablet pen. much better than windows vista. Also, with a bit practice, you can use LyX or any other equation editor, combined with Leopard's hand-write recognition. Just an idea
Win7 has MathInputPanel application; if you have digitizer, you can just draw symbols as you would on paper, it will recognize the math. Of course, advanced payment of MS tax is required.
Slashdot user, which can't recover lost password from Slashdot.
Back when I was taking math classes, I used a program called TeXmacs for taking math notes. It's a (almost) WYSIWYG editor with a well-designed system for inputting equations, using sensible key bindings for all the common mathematical symbols and operators.
Despite the name, it's not related to either TeX nor Emacs. But it does use TeX's fonts - which result in equations that are almost as good looking as the ones from TeX.
It worked fast enough for me to keep up with all my math lectures.
I don't understand why you dismiss MS Equation Editor out of hand. I find this universal derision everywhere, from grad students to professors. If I tell a professor I typeset my homework in Microsoft word, he or she will often give me a disbelieving look filled with disdain.
I have been using this software to take notes in math classes for the past five years now. It's remarkably simple to use. Just type "alt+" in any word document, start typing mathML shorthand, and it pops up instantly, with none of the syntactical fluff of straight LaTex. Plus, the shorthand symbols of MathML and LaTex are nearly identical, and you can interleave equations with Excel charts and Word drawing primitives (something EXTREMELY useful for physics.)
I have horrid handwriting, and write extremely slowly, so typing things out in MS Equation Editor makes things about twice as fast and much more readable. I also typeset all of my homework that involves math symbols in MS Equation Editor.
Pen (that thing with ink you hold in your hand) + paper (that stuff we use in printers to put ink onto) = writing equations quickly.
Come on computers are good but ever heard of the right tool for the job?
Mathematica suprisingly has a very decent set of formula editing shortcuts, see for example this link. You may be able to export to LATEX or other formats, I cannot remember. Of course, that is one hell of an expensive text editor.
Buy a cheap wacom tablet, and use Microsoft's Math Panel Input Editor on Windows 7. Amazing recognition of handritten scrawl to MathML equations with preview and quick-fix for any element.
And the laptop in class has all the other advantages you'd expect - digitized books (legit and otherwise), browser ("What did the professor mean? (google, wikipedia) Oh, that's what he meant.") Even streaming music into my headphones to keep me awake during my one evening lecture.
The one place I haven't been able to use the laptop for notetaking has been the math classes, for the exact reasons the OP mentioned. I burn through a dozen single-sided pages in a ninety minute class just so I can write big and keep it all legible. I'll be checking out LyX (once they're no longer slashdotted) and some of the other recommendations.
And yes, I am upgrading the laptop (soon - the battery's crapped out.) I was considering a tablet just for the math classes but it sounds like there may be better alternatives. Unless anyone cares to recommend a good tablet?
Besides - how many students are even now trying to work out how they can take all their notes on an iPhone?
Prisencolinensinainciusol. Ol Rait!
Why is this information not already available in digital form ahead of time?
Would it not make for more productive class time if the students could print the notes for the class before hand and then spend the class time trying to understand and ask questions then instead of taking the notes and then asking questions the next class?
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.
As far as I know, it's still a going concern. Don't know how much development is still going on with it. I haven't worked there since 1998,
Please do not read this sig. Thank you.
TeX or LaTeX with some prewritten templates you copy from class to class should be pretty fast with practice. In addition to TeX macros, you can define keyboard macros in your text editor, so if you, say, type alt-i you get \int_{}^{} with the cursor in the first braces. You can also write a perl or even sed script that runs before TeX to remove the need for some of the backslashes--e.g., it could replace "sin" with "\sin" within equations (and in the rare case where s, i and n are variables, you can space them).
microsoft *pain*.... fix that for ya.
There have been significant changes in Win 7.
This version uses the ribbon UI, adds brushes and anti-aliased shapes, which can be resized freely until they are rasterised, supports alpha channel transparency for PNG and ICO file formats and saves in the PNG file format by default. Paint (software)
I'm a math grad student and so far the best bet I've found is vimlatex. It's a package that adds a bunch of macros to vim to speed up latexing.
For learning math, not for mere calculations:
I never use separate papers any more, because after a week of intensive studying I can never put them in the right order.
I never use a pencil, it doesn't look well and it doesn't feel right.
Also I use multiple colors whenever possible.
A good notebook of your own is worth having, and nowadays you can always get computerized lecture notes from some of your classmates.
How about recording the lecture using a cell phone and otherwise pay attention to what the lecturer says. You can then take notes from the video or audio.
Sorry my bullshit sensor overloaded.
Grapher is the "version" of Graphing Calculator that currently ships with Snow Leopard, I don't know if it's too clumsy for quick transcription. As for TeX based stuff... I gave up in-line typesetting in the eighties for both proper layout and old-school word processing... *shudder*.
I did CS with a minor in Physics, so I took just about every math class there was. I, too, wanted a way to take notes electronically. I tried just about every method, and in the end I think pen and paper is the way to go.
I used a precursor to the IOGear Digital scribe - basically a regular pen with an ultrasonic transmitter. There were receivers that detected the pen's position, so you could in effect turn a regular notepad into a digitizer. Quality was ok, but there were occasional mistrokes and the resolution left something to be desired.
I actually took notes in one particularly equation-heavy neural networks course entirely in vim using LaTeX. It was interesting, though somewhat harrowing. Missteps with my editor or not remembering syntax did occasionally leave me getting behind and missing something.
Honestly, I think the best answer is just to take notes on paper and transcribe them later, either into LaTeX syntax or using an equation editor. You'll learn and retain so much more that way.
If you're like me you probably type normal text faster than you can write it legibly.
For the plain text part, you'll probably want to stick with the computer.
For the equations, type in a cross reference id like "eq15a" and scribble the equation onto a small pad of paper and write the id in the margins.
At the end of the day you can just insert the equations into the computer at a leisurely pace.
Alternatively, learning shorthand might be allow you to take notes on pen & paper sufficiently fast. I haven't tried it myself yet but it seems promising.
I use this daily now, wish I knew about it in college. It allows equations to be put in very quickly and has the added benefit of being "live", which means it can actually perform the calculations. From an engineers point of view the best feature is it's ability to work with units.
In terms of speed everything has a shortcut assigned and the equation appears as you type it.
I took notes in LaTeX for all four years of college, including upper-level math and CS courses. It worked fine for me. Once you get used to it, typing most symbols is just as quick as writing them. Long formulas or lots of embedded fractions and things make it more difficult, but you can still type it pretty quickly, especially if you don't worry about compiling it as you go (which I did, and which was perhaps a bad idea since it does slow you down).
As some other people here have suggested, you can also define new commands to help you. One class I was in started using a lot of diagonal matrices, so after being slowed down a bit the first time I defined a new command that would easily let we write diagonal matrices. You can similarly define new keywords or languages or whatever you need to help you stay on top of things.
It might not work for everyone, but if you type fast and know LaTeX well it is easy and can work well.
Grapher is pre-installed in your Utilities directory. It has a pretty intuitive equation writing input. However, it does not support everything -so it may not be perfect.
If FSM had wanted us to write by hand, he wouldn't have invented the typewriter.
Maybe OP is asking the wrong question, how about asking your instructor to print/scan the note for all the students? After all, students are the 'consumers' in class, especially given the relatively high cost of University education this should have been a given (assuming that it is in a country that wasn't free).
Comment removed based on user account deletion
I am not a math major but my chosen field requires some understanding of math (go accountants!). My solution for complex graphs, math equations, and symbolic images was simple. I took a digital camera to class, asked permission to shoot digital photos with the flash turned off, and then transcribed the material from my digital images after class.
If I am taking text notes I would make a notation when I took a picture so I would insert it later. Otherwise, I would just listen and every once in a while shoot a shot of the dry erase/chalkboard.
You probably can't type / draw fast enough to keep up with a fast presentation.
If you have a netbook/laptop with audio and a small webcam, the best option may be to just record the
audio and record the presentation as a video recording as well. Then you can go back and improve your notes for any sections you didn't get a chance to fully transcribe or understand at your leisure.
If the presenter is operating off of a power point / slide deck or uses any kind of recording white board or is having their presentation taped then of course you should ask for access to the media directly from the presenter since it will probably be the highest quality and easiest to use material.
IMHO there is no good reason to be distracted trying to make a rote transcription of a presentation which you can barely keep up with -- that's a sign that something is wrong with either the presenter not presenting things in a usable format at a reasonable pace of information density, or a sign that you should be using some other technique to get reference materials from the presentation. Your attention ought to be focused on trying to understand the big picture and not transcribing furiously.
What about getting a small, good quality webcam, preferably with a zoom feature? When your professor writes out an equation, point the camera at it, take a quick screen capture, and paste it into your notes.
Seriously. Just stop trying to type notes. We both know you're just dicking around on facebook. Just take notes with paper. You can write equations, draw graphs, and whatever else you want, including little stars and hearts next to your favorite equations.
If for some reason you really need to type your notes, do it after class. You have a problem of your own making.
I completely agree with this. I did exactly what you suggested when I was in school. If you went to the computer lab there was a scanner with a document feeder available. This was a number of years ago now; these days you can probably expect to find them in every academic building on campus. In my case I was in Information Science and Minoring in Comp Sci so I was always near the computer lab anyway.
For those class where I could not just keep a terminal window open to my shell account and type my notes and or for classes like math or Computer architecture where I really needed to sketch things this was they way to fly. I just scanned it to tiff after class and copied it to my home directory.
It was great because I could review my notes anywhere on campus and just fetch them to my home system via ftp with a shell script each night; never had to carry around much of anything.
Repeal the 17th Amendment TODAY! Also Please Read http://www.gnu.org/philosophy/right-to-read.html
Most math, physics, and engineering textbooks leave important equations as an "exercise for the reader." The tradition is surprisingly pervasive--I've had to search through as many as a dozen books trying to find certain formulae. This makes it unnecessarily difficult to find key information if one hasn't taken notes in class, or when coming back to the text for reference or review.
Plea to instructors and department chairs: Please choose textbooks that can serve as reference resources to your students as they study and after graduation. Plea to authors and publishers: Please include all of the central equations, and use formatting to make it clear which equations are "universal" and which are example or special-case equations.
A cheap Wacom Bamboo (100$ or less depending which one you get and where you get it, can go a fair bit lower with some looking) does the trick.
Use Office OneNote 2007 (2003 not worth mentionning) if you want to do everything manually, or if you want to input them and have character recognition, Windows 7's handwriting recognition is vastly improved over XP's and Vista's, and can handle equations fine, though for complex ones you may need to train it a bit.
Use LatexIt on a mac (simmilar is EquationService). This is a service. so you are in a text editor like textedit.app or word,. you type the latex equation, then execute the equation service from the services menu (using an assigned command key). it changes the latex to an equation and pastes in the graphic in the same spot.
you are typing latex, but your are not screwing around with creating files and latexing them.
Another realtime latex on a mac is grapher.app
Some drink at the fountain of knowledge. Others just gargle.
Give it up on tech solutions; Math is best done with pen ad paper.
It's cheap, fast and accurate to the same extend as you are..
During my years in university, it was recommended you take notes, and work out your own notes afterwards. That was half the learning of it. (They even gave timescore points for it on my university if you did it or not)
Copying it from the bord and not doing it yourself will not teach you anything.
Learning Math (we are talking real Math here, not calculus) is getting into a routine, learning and doing it again and again, on paper, yourself..
I'd stongly advise AGAINST using a tool to learn Math..
(Like using a calculator destroys ones ability to do even the simplest sums)
Get over it, nothing in life is for free. No pain, no gain..
Cheers,
Take a look at the Freehand Formula Entry System (GPL). Handwriting recognition for mathematics.
I recommend it, neat and clear language, many packages use it as intermediate format.
Have you thought of adding footnote type markers to your notes and then writing the equation(s) down on paper. Later you can add them into your digital notes.
Word 2007 has a hugely better equation input (including latex-like input).
See this post for information:
http://blogs.msdn.com/microsoft_office_word/archive/2006/10/04/Equations-in-Word-2007.aspx
In a few months, Office 2010 will be out, which adds the same functionality to Onenote (which is one of the best note-taking apps around), as well as PowerPoint, for those times when you nede to present your data. :)
Try EXP 5.0 or Scientific Word
You may think it's too slow now but it pays off in the long run in a big way. Typing LaTeX in real time requires you to examine each statement in your mind to select the correct LaTeX code, this helped me with memory.
If the speaker is using powerpoint/beamer/transparencies/etc. you're probably doomed, but in that case you should just be able to ask them for a copy of their presentation anyway.
If the speaker is using the chalk/whiteboard, then I'm serious--I've seen people take notes in Latex (including equations and such) far faster than people can write them on the blackboard, so it can definitely be done (and in just an ordinary text editor). It's really hard though, since when you learned to touch-type, you probably didn't have to type so many $,\,&,(,etc. quickly and it can be tough learning to do so. Having good macros is obviously important.
That being said, is taking notes on the computer really a good idea? I personally don't really end up looking back at my notes, so I find it's more useful to write down (by hand) just enough that I'm staying alert and reinforcing the most important points in my mind, but not so much that I'm writing when I should be listening and thinking.
If all you want is to insert a bit of notation in a readable way into a document, copy and paste is your friend. Pick a nice comprehensive page such as this Wiki page which may have most of what you need.
Make a static local copy of the HTML page for speed of access and copy the bits you need into a scratch pad, blank word processor page or paint program. (If you have a Microsoft OS use OneNote instead for its nice screen scraper - it's a reasonably nice virtual notebook by the way, used it for years, but be careful with it).
Once you have it right copy the lot as a drawing and plonk the lot into your document where you want it. It's not MathCad, it's not LaTex, but it's reasonably fast, there's no separate program environment to bring up, works and there's really nothing to learn.
I've always been a fan of simplicity, and sometimes your own hand-eye-brain interface is the best one for the job. But if you do this sort of thing a lot, survey the field and buy something purpose-built. I grew up on Fortran though and a bit of hack and slash is second nature to me, so your mileage may vary. TWAGOS.
Do not mock my vision of impractical footwear
Me, I have great difficulty taking notes and paying attention to the instructor at the same time. ADD or something, you know? I should really get a laptop, because I can type without really needing to even think about it.
Property is theft.
Forbidding notes is discriminatory against visual learners. You may not derive much benefit from the process of writing notes if you are primarily an auditory or tactile learner, but that doesn't justify claiming that everyone else would be better off without notes.
For a visual learner, the process of writing the notes is often more important than whether they are read later. They are a way to organize ideas or anchor them in memory and are not just a recording device.
You can type, right? Unless you use non-keyboard input I'm not sure how you're going to do better than LaTeX for math input.
If it is slow you are doing something wrong.
f_X(x) = integral(-infinity, infinity, f(x,y) dy)
This is $f_X(x) = \int_{-\infty}^{\infty} f(x,y)dy$, to a first order approximation that is good enough for notes or even homework. That's fewer characters than your example!
Obviously, especially if you're a novice, you might not know the commands to do what you want -- but you can always fix up the syntax later.
An Apple Newton. It has a steep/shallow (delete as appropriate) learning curve!
I understand slashdot loves to use fancy technology to solve simple problems, but sometimes simpler is better.
And sometimes taking notes on a computer is simpler than recording them in a dead-tree notebook.
I'm not a student, but I do take a lot of notes as a technical writer. When you have as many notes as I do, having them in online form can be a lifesaver. Not only are they easily searchable, but the disorganization that creeps in when you're taking them (you're more concerned about getting all the facts down than about keeping your notebook in order) can be easily remedied.
You can, of course, take notes on paper and transfer them to computer later. (That's an obvious solution if you're recording math or diagrams, and don't have a tablet computer.) But that takes extra time, and if you're busy you may well forget to do it. And then some crucial piece of information exists only on a piece of paper you can't find.
The question here is not "is this technological overkill?" The question you need to ask is, "what works for me?" If you're good at keeping (and using) pencil-and-paper notes, fine, do that. But not all of us are. For us, the high-tech solution makes sense.
Why are you taking notes in Math class? Personally, I think it is better to just pay close attention to the lecture and absorb all of what is being said and focus on thinking about it and understanding it. Textbooks (and or other references) will have better "Notes" anyway. I always did this in every Math class I took (except from that which I taught myself and CLEPed out of): Calc I-II-III, Linear Algebra 1 & 2, Discrete Math 1 & 2, Topology, etc. I always got an "A". I never took a single note. That doesn't mean I didn't study or have to work. I focused my time in class in paying attention to what the instructor/professor was saying and doing rather than writing. Then, I went home, read the book/chapters in detail and worked through the exercises and problems diligently. Sometimes it was easy, sometimes I was up all night.

TC1100 Tablet computers are running as low as $300 on ebay. I use one of these paired with OneNote 2007 and it works pretty great
I've been using OneNote for a couple of years, and I'm pretty disgusted with it. Too complicated, too limited. too unreliable, too many "what were they thinking" gotchas.
Right now, I'm giving Evernote a try. Not as many snazzy features of OneNote, but the features it does have work well and are easy to access. And it's free, if you don't mind a few non-obnoxious ads. If it continues to bear the strain, I'm transferring all my data from OneNote and deleting the sucker.
Pen and paper is very useful, even when you end up just copying it verbatim to a laptop later.
:-).
First off, writing it down the first time make you more likely to remember the content than if you just sat back and listened (same as if you used a laptop). And when you copy it to a laptop later you again will be more likely to remember the data, maybe more so this time as the concepts have had more time to sink in.
Second, not everything is a formula or text! There will be curves, surfaces, diagrams, and so forth all drawn on the white board (or black board
Third, the paper will last longer. There may be times, decades from now, when you'll want to review some old class material. You paper will have survived, but your 2009 file formats will not, and the media may not be readable (the laptop will have long since died). I've got some class info on 9-track tape still, but I don't think I'll be reading that anytime soon. Or the programs I have on 8-inch floppy, assuming it isn't moldy from being stored in the garage.
One useful answer and a billion posts arguing the relatively insignificant semantics/grammar/meaning/etc of a sentence in that post. Sure, it makes for good discussion, but it's so bloody useless. (I'm just bitter because I don't have enough mod points to give everyone a big fat "off topic".)
I foolishly tried once to that once, with LyX - pretty cool concept, but when you really need to write a whole bunch of equations in succession, then you end up putting more effort on getting it right on your computer than on actually paying attention to the lectures. Don't believe it? Try using LyX to jot down long-ass operational semantics formulas while trying to pay attention to what the instructor is saying.
Best thing is to jot them down on paper for later digitizing. Or use a Baboo Pen in conjunction to your laptop (I wish I had that kind of technology that cheap when I was in school.) Actually I might end up Xmas-present myself with one of those.
In my experience, Mathcad is an excellent choice for producing professional-looking equations without delving into latex. The hotkeys make equation entry a snap, and the equations look exactly how you would write them (as opposed to mathematic or maple). The only complaint that I have is that there is no Linux version...and their license scheme is a little bit draconian. But if you run windows, I highly reccomend it.

Mathematica has keyboard shortcuts for every math symbol I have ever used. Any kind of palette or input box is just wasted time with the mouse. The two universities I have been a part of have had a free student license.
For instance here is the intergration symbol
http://reference.wolfram.com/mathematica/ref/character/Integral.html
your example requires 4 shortcuts which is entered
f_X(x) = [ESC] int [ESC] [CTRL]+[-] - [ESC] inf [ESC] [CTRL]+[6] [ESC] inf [ESC] f(x,y) [ESC] dd [ESC] y
heres is a list of all the symbols

I am grad student in Physics. I am also an obsessive geek and I want to put everything in my computer to easily organize them. Also I don't like papers or pads because I can easily misplace it. I want to put everything in my computer that gets backed up everyday to two different places.
I've tried many different things to find the most efficient way to write down math equations. In the end, nothing beats paper and pen. Especially when I just have to work something out, or do some calculations, paper and pen are really the best tools. Using computer when you try to solve something analytically, unfortunately, is often a distraction, because it can keep up with what's in my head and becomes a bottleneck.
I transcribed the most important things with LaTeX, but for the rest, I just bring a single notebook / notepad on to which I write everything down. Then, after I finish the notepad, I cut the binding and scan the whole thing and then organize it.
So my suggestion: paper + pen + a multifunction printer/scanner with automatic document feeder (ADF). You can get one of them for about $100-$200.
I teach electrical engineering and have been watching this in class. The only students who successfully take notes using the computer have tablet computers and use the stylus. One student I talked to about this says he is really happy with it and would be completely paperless if the professors didn't insist in turning in homework on paper.
I have seen many different types of digital note takers that will store many pages of hand written notes. These are often stand alone devices that do not require a computer to input stuff. Then later you plug it into your computer and download the data. Many come with OCR software. Do a search on IOGEAR MOBILE DIGITAL SCRIBE for an example (note, I have not personally used any of these devices).
I've been using my laptop for a few years at university classes, and always found that the Formula object in Openoffice Writer is perfect for my needs.
The downside is you have a learn the names for your most popular symbols or operators in your equations, but learning it is quick and once you know it, it's possible to type in formulas about as fast as the teacher writes them on the whiteboard.
Perhaps your courses require so MUCH equations that this will not be a practical solution, but for the few mathematics classes i've had, it was fine. I could keep up, and they look gorgeous.

I don't see the problem; it seems like you should be able to easily beat the Prof. at writing equations with a (good) text editor you know well and LaTeX.
With the AUCTeX mode for Emacs, you get lots of shortcuts (like 'electric' backslashes and quick commands for environments) plus in-buffer previews.
Add in judicious copy+paste and you should be able to run circles around most professors writing on a blackboard and have plenty of time to read slashdot comments. If they are using an overhead or powerpoint, it might be a little trickier, but hopefully they are handing out notes.
Have you considered using a Mathematica notebook for note taking? Many campuses have student/site licenses for it.
Pearson's TestGen which has a really sweet equation editor, inline and live in the document...
Except that it's strictly point and click, no keyboard shortcuts. I would like to think they'd have the sense to publish a document editor based on the same technology... it appears my waiting has been in vain.
But, MathType is actually available to purchase by real people and does a perfectly good job. I prefer TestGen in most other respects, but that probably has more to do with use time than objective analysis.
Seriously, for stuff like equations, quick-and-dirty diagrams and the like nothing beats a pen and paper. You can type it all up later if you like - in fact going back over the material, retyping and summarising is a great way to learn - but for spur of the moment, need to get it written down now stuff it's hard to beat the old pen and paper combo.
....typing really fast?
1) You never had an instructor talk about something not in the text?
2) Personally, I find taking notes during lecture (or reading a text!) helps me retain the information, even if I already have my own record of what's being discussed.

Write your notes on blank paper (not lined and as white as possible) with a dark pen. Take a picture afterwards and throw the paper away (or do some origami [1]).

I take my notes for physics and math in LaTeX. You should just get better. Much cheaper.
Get an inexpensive drawing tablet, turn on Ink in OSX (10.5 and up; at: System Preferences: but note that the preference pane will not show unless you have a graphics tablet plugged in). Write the formulas on the tablet.
You can take screenshots (Command-Option-3 full screen; Command-Option-4 select an area to capture) to save what you write/draw and use Ink's character recognition to convert it to formulas with a check via the saved screenshots to make sure it didn't make errors. You can turn the character recognition off or on anytime via the Ink preference pane.
You will want to enable the Character Palette (at: System Preferences: Keyboard & Mouse) so you have quick access to the mathematical symbols in your chosen fonts for your saved notes.
If that's how you, as an individual, learn, then whining about it and trying to get the professor fired for failing to accomodate your special needs is a selfish jerk thing to do. If you're that special the obvious cure is to skip physical attendance, take the handouts and the video and transcribe the event at your leisure.
But no, you're enough of a jerk to impose the limitations of your special needs on all of the normally abled people.
Help stamp out iliturcy.
I know it's common to not RTFA, but try to RTFC that you're responding to.
Note taking, for me, was to summarize what the teacher said, in MY words so that I could understand it later.
Heaven forbid ever become an engineer, where the teacher is drawing simply supported beams on the board...
Both were points to "you're trying to reinvent the wheel". If he's having problems with Equations, he'd never survive where they actually draw stuff.
It is windows only, but you can in theory enter the formula fast
then go on to notes. There is a small amount of syntax to learn, but it works good. I used in it collage for engineering reports before my army days.
If you're using Windows, try EXP 6.0: EXP 6.0
It's the best mathematical editor that I've ever used, bar none. The shortcuts are easy to remember, the buttons and toolbars are intuitive, the tab stops are just right, and it looks exactly like you would expect when printed. I like the word processing features available with it too, like paragraph spacing and pagination. This is how Word's equation editor SHOULD have been built.
I thought the syntax in your equation looked somewhat familiar, but it's not quite it. Have you tried using the openoffice equation editor? Or, for that matter, in a text doc, just insert a formula (alt-i -> f or something like it for the shortcut). It lets you enter an equation using a simplistic syntax, and then shapes it to look "real". Admittedly you may need to judiciously learn how to use the parentheses and square brackets to make it work right. But I did that for some of my advanced math classes, and it worked like a charm. It really makes life easy, and it automatically adjusts the size, lets you do multiple lines etc. There's a little "tablet" of standard functions, but once you learn the keywords and figure out how to use parentheses to make it select the right thing it'll become easy and accurate. Cheers.
---- I am certain of only one thing : I know nothing else.
Pencil and Paper buddy. Pencil and paper. No one involved in high-level math writes stuff down on a computer until it's finished. No serious math student takes notes on a computer. Plain and simple.
Whatever advice people here give will work for certain rigid examples, but inevitably you will find some subtle math notation that you can not accurately express in any computerized form (that's at all quick).
Have you tried the new Math Input Panel in Windows 7? It automatically converts handwriting into mathematical equations.
If anyone gets to the 495th or so comment, as a former mathematician, I recommend a pen and paper. If it helps you to have it in ASCII text (for searching, etc...) then take a few minutes at the end of the day to transcribe it.
My rationale -
A) Basic mathematical notation has evolved over a few hundred years to be concise and easily manipulated. It once was that equations were all described in text, so that even the description of the square root of a number was cumbersome ('a quantity, which when multiplied by itself yields the original...'). Expressing mathematical entities in textual psuedo notation, while quite a bit better than in prose, is a step backwards.
B) As you get more advanced in mathematics, you will most likely find the need for diagrams anyway (depending on the field). For instance, commutative diagrams in algebra, or all the bizarre pathologies in analysis (such as the 'walking ghosts'). There may be packages to do specific kinds of diagrams, but they will likely be unwieldy.
So get a nice pencil and paper. Or, like has been mentioned many times in this thread, get a Pulse pen. It's no worse than a pen ('cept for price), and you might find it useful.
(mini-review)
I recently got a Pulse pen, and while I'm no longer taking class notes, it's quite handy. It's a tiny bit large for my hand, but fairly comfortable still. You can search for the textual parts of your equations, and it mostly finds them. I've downloaded the MyScript OCR free trial (for Mac), but I don't think I'll buy it, since it does a poor job with my poor hand.
I love how everyone here is telling you to just pencil and paper. For the past 7 years (through both college and high school), I have taken all of my math notes in Mathematica. Every symbol, even the most esoteric ones, is at most four or five keystrokes. For example, an integral like integral x=0 to inf (x^2)/xbar is quick to enter:
integral template -- ESC i n t t ESC
bound -- x = 0 TAB ESC inf ESC
value -- x C-6 2 RIGHT C-/ x C-5 UNDERSCORE
it's really quick to type, and you'll quickly learn the keystrokes from the character palette. I haven't taken a single note on paper in any of my math classes since about sophomore year of high school.
--Quentin
I used grapher (in the utilities folder on OS X). Fast enough for me, and it doesn't take a lot of training.
Integral = option-b
infinity = option-5
sum = option-w
(did you know slashdot strips special characters?)
It handles where to put all the numbers after you get the symbol in very well. You can right-click to copy as latex (or text), but I always just dragged them into my document, which brings it in as an image, which was good enough for me.
Bonus is that it will graph stuff if you put it in in the correct format.
http://www.homeschoolmath.net/worksheets/equation_editor.php I use this often when I'm preparing notes, and formula sheets.
As a OneNote convert, I'll tell you why I use my (work provided) tablet instead of pen and paper: I can mix digital and handwritten content and I can write well enough for my handwritten notes to be searchable. Also they are all backed up and I don't lose them. Not to mention I can write in pretty colours easily and I don't have to carry anything else around or worry about pens running out.
I know it's the new cool thing on Slashdot to point out that tech sucks compared to old school solutions, but there are real tangible benefits for some things. Why must every topic on here avoid answering the question and turn into people having a go at the person for wanting a tech solution from a tech website?
Also, regarding your point about photocopying notes, there is significant research that the act of writing or typing something helps to commit it to memory as it involves more senses than simply looking at a pre-written text.
Just make it surreptitious and record relevant things.

If you're serious about taking mathematical notes, there really isn't anything to beat LaTeX except for the multi-mentioned writing tablets, where you're essentially recording images (and could do the job just as easily with pen and paper).
If you're worried about your typing of LaTeX taking too long, make macros. It's trivial to create commonly used macros for "long" things like \int_{-\infty}^{\infty} so instead, you type \iII (i - i-cap - i-cap) or some other easily remembered name. If you're still typing out every bit of math you do in LaTeX long-hand, you aren't coming close to using the true power inherent in a markup language.
Want easy ways to represent \mathbb{R} or \mathbb{C}? \rS or \cS defines work great. Integrals? Same idea. Just figure out what the commonly used things are in the class you're taking notes for, and make macros for that.
I had surprisingly good results with LaTeX maths in a Mediawiki. In a wiki you can get down everything but the math very quickly, and as others have said it is not too difficult to become speedy with the actual latex math.
I took my undergraduate signals and systems class with this method and never lifted a pencil in lecture. I'm sure the professor was probably a little confused, but in the end I performed well and now have excellent notes to refer to. I also had success with this in a number of other classes, but certainly not ones which require lots of graphs or matrices: the markup for these items is too verbose and I quickly reverted to pencil and paper.
A small wacom to plug into a USB port, easily carried in your laptop case.
There is a wonderful mac program called LaTeXiT. It basically lets you type latex directly into a very small editor. The results are compiled and displayed in another window and you can drag the result into your favourite notetaking program.
It's pretty neat.
That said, in a lecture, I still prefer my pen.
People who like to take copious notes generally also like to study from them. Having the notes searchable is kind of handy. Also, you can take even more copious notes in most classes if you're typing.
Personally, I hate taking notes in any form and never do it, but I know people who basically see classes as an opportunity to act as stenographers.
I've done about 8 years total of various Engineering classes. The first year or two I used strictly pen and paper. The issue there, is your work isn't search able. You may have some idea where what you want is based upon when in the class it may have been covered, but searching is crucial.
On the other hand, as has been mentioned, there are really no perfect solutions for equations and images. I settled into a hybrid approach. Sentences and text got typed into my laptop using a note editor of some type. I used AquaMinds' NoteTaker (Mac only), but One Note seemed to work equally well. Equations and pictures were numbered and handwritten on a separate page, later scanned into PDF and inserted into the notes for the day. It worked reasonably well and was essentially free, given you have a computer and a scanner available. With the quality of built-in laptop cameras improving, that may even be an option as a rudimentary document scanner.
The Pulse pen, while looking pretty nifty, is expensive and requires special paper. Not exactly ideal, either.
...have either a pen and notepad to write down super long equations that you cannot type quickly in class. In your tex file, just type a little note (make a macro that increments some sort of equation counter) that says "formula here" and then just copy it into your tex file once you get home.
Could you use a device with a built in digital camera to take a photograph of the finished black board or once every few minutes, then rewrite your notes by hand or type them up in lyx afterward at a more deliberate pace, thinking about it more as you go along? I would think you could then listen and pay close attention, feeling a little bit more relaxed and less frazzled, especially if the prof's handwriting is rapid
I am now using latex for a long time (14years). I have been using and testing equation editors. My experience says: after some training and fitting macros in your emacs (or vim or whatever texteditor you use, not to offend the religiuos feelings of other people here), you will be faster in latex, because you dont need a mouse.
On the other hand, you will not be as fast as writing it down by hand. There is no way you keep up with a math prof writing full speed handwriting on the blackboard AND listening to what he says. For some equations yes, but (i studied physics) i am pretty sure that handwriting equations will be faster than typing. If you want to digitize it (undestandably), use a scanner or a graphics tablet to take the notes.
I'm in a biochemical engineering class where we need to write text notes as well as a large number of equations with an abundance of symbols, all from quickly vanishing slides. I type the text on my laptop and leave references for the equations. My friend writes only the equations -- by hand. I borrow her notes, fill in the equations in my own time, and send her a copy. Now both of us have neatly typed notes with nothing missing, all achieved using nothing more sophisticated than MS Equation Editor, a pencil, and cooperation. It works, and the learning curve is flat.
Karma fed to this user will be promptly burnt. Be warned; be wary.
I agree. For my own mind, an audio recording device is specialized enough.
Paper/Pencil let the subconsciousness and conscious work as a team, while electronic separates the two. This makes fuzzy and logical classes harder, because the mind visualizes the equation working(creative mixed with logical reasoning).
Though if the instructor has a political opinion and mentally wants their students to be parrots, then electronic can be useful. Much like memorizing an opponents chess moves.
I have never attempted this, but here is a thought.
Use --> http://www.fontcapture.com to easily create your own Font, though it will take precision and care to make your font seamless (I recommend taking the time to digitally create the font rather than simply writing the symbols in the boxex). I believe keyboard layout will be easily learned and save great time.
My thoughts:
1. keep all non-shifted keys as normal -- this will allow you to take notes about your work and supply all variables
2. make shifted keys to display special characters -- this could be your functions, greek alphabet, superscripts.
-- examples:
-- x^2 would now translate to x(Hold Shift)2. But the font would already place the 2 in superscript location.
-- Instead of (Shift + Dash) being _ (Underscore), it would now be the approximate symbol.
-- Instead of writing integral, you simply type (Shift+i) or make (Shift+n) show integral sign, so you can use (Shift+i) for ^i.
-- pi could easily be typed as (Shift+p), lambda could be (Shift+l)
-- Partial d could be shown by typing (Shift+d)
-- Square Root could be (Shift+Q)
-- Integrate could be (Shift+T)
-- (Shift+n) could be sub-n
Sorry I gave so many examples. I know that you understood my concept early, I just got carried away with thinking about the potential of the format.
Also, if anybody considers this of value and would like to work collaboratively to produce a quality and well thought out font for this purpose, shoot me an email --> hof.dig@gmail.com
Thanks for your time and consideration and have a good day.

Easy: Stop trying. Get some paper and a nice pencil. I went a little overkill and got one of those smartpens. Either way, paper > computer in this case. Spend less time thinking about writing/input and more time about the problems at hand.

I HATE people who takes notes on their computers. Can't file your notes in the correct order? Try writing the date in the corner of the page. Make a table on contents for "easier searching," although I for one have never found it that hard to find the day we covered a certain topic, even in an eight-month course.
Seriously, the hum of a single laptop behind me in a lecture is like needles on the brain. Don't be that jerk.
Still the fastest way. Then retype your notes on the computer when you get back home. The quick refresh on retype is also good for your memory.
"I'm never quite so stupid as when I'm being smart" (Linus van Pelt)
When I was in college, we used a P.E.N. It worked reasonably dependably, was inexpensive, didn't run out of batteries and used up very little space on the desk. We used it with P.A.P.E.R, which is a lot like a LCD screen, except that the blurriness that occurs when you press your thumb on where you've written would only happen if you'd written recently. After the pixels had been on the paper a while they would become permanent. You could also play games with it. My favorite was tossing them up so they'd stick in the acoustical tile in the ceiling. There were also fun games with drawing space battles and one can hardly forget the fun you could have firing small paper projectiles through the casing.
In the second semester of my first year, a friend introduced me to the idea of recopying my notes for clarity in your spare time after class. This is something akin to printing out your notes, except that instead of committing them to paper, it helped commit them to brain. This proved useful later when the test came along. I'm not quite sure if college is still about learning, or just mastering unnecessarily complicated tool chains --- it is difficult to say these days which offers the better early life lessons -- but if college is still about learning (and beer, no doubt) then I'd suggest the P.E.N. approach. You can recopy your notes into TEX later if you want.
Can you get an "A" for typesetting these days? When I was in high school it was thought that the glossy bound report was the surest to win the teacher's heart, but I can't say there was a rigorous double blind study.
Besides pen & paper LaTeX is the way to go. Initially your speed will be slow, but you will be amazed how fast you can type when in full flow.
Additionally you may use macros keyboard macros to speed up even further!
In my experience, typing equations involves a certain amount of mental effort, as it is something which (at least for me) is not a familiar enough process as compared to writing, in which I have had so much practice, that it is a subconscious process that does not require effort. I think this lack of effort leads to more focus and reflection on the subject matter and aids understanding.
It seems that recommendations are a personal choice by everyone.
Latex, Lyx, Mathematica etc are all possible
Lectures with notes are great. Lectures without notes are not so much fun.
Interactive engaging lectures where you can ask questions are important - forget tat your question is trivial
as far as someone else is concerned - your measuring stick and theirs are different - but you want to know
an answer - so ask.
If I have to make a choice between note taking and paying attention - I know that some lecturers talk or write
so fast that no note taking speed freak application or pen+paper solution can keep up - so I choose to pay attention.
If the lecture is slow enough - I would use my Mathematica - it is familiar. I would not go out looking to learn anything else - just to take notes.
If its too fast - pay attention and only scribble down the essentials.
Now if you came to a point where you were producing lecture notes for students - there is the real question.
Me personally, I would use Mathematica - why ??? because there is the mathematica player and it has really nice print-outs. It also has
one very nice feature - symbols that look the same can be hovered over and the underlying reference will appear.
Reals, Regions and Reimann might all be represented by a classic 'R' of some description. How do you tell them apart ?
Another reason to use Mathematica for creating lecture notes - you can change some parameters for each lecture
so that you canmake it seem simpler or harder depending upon the type of people in the class.
Lecturers probably use chalk and talk a lot because they get asked questions - and chalk and talk is flexible.
Lecturers who have been around probably get asked the same questions a lot. Simpler examples may be nice
but a more complex example sometimes answers the question of "how to make it work when you have complex equations".
Some students can not easily jump from a simple example to a complex example - they deserve to get some
guidance on how to treat a complex problem like you would a simpler one.
If I have to teach an budding engineer some maths or physics - I like to make sure that they get better than 95% in tests
because they worked their butts off and because when they build a bridge I might drive over, I want it to be built like a
brick, nice and solid and reliable.
One student was going to sort of cheat - using C++ code fragments from his mates - yet he already had his own code with documentation
and he understood all that he had written. He opted for his own work. I liked that about him.
Take photos of the blackboard and then transcribe them later. Why didn't any of you nerds think of that?
I see there's a naysayer getting modded up for contradicting you. However, in my second or third year of university, I figured the same thing out on my own. Instead of taking copious notes and having my attention divided, I just concentrated on the lecture, asking questions where appropriate, and hopefully did some preparation on the topic beforehand. The result was that I retained mentally a lot more than I could have set down to paper during a short lecture.
As you say, most professors also made their own notes available for students that wanted them.

I find the syntax of groff's eqn macro to be easier than LaTeX.
In my latter engineering and math classes, I spent a great deal of time in Octave and Maxima (more like a FOSS solution to Matlab and Maple) I found that I started to take notes in a Classic text editor and would write equations in either the code of what ever tool I was using (Octave / Matlab for the engineering courses and Maxima for symbolic equations and Math courses). The beauty of this is that you can easily run them in the program without the need to reformating them and the programs would put them in textbook / pretty-print format for you.
Slow Down Cowboy! It's been 1 hour, 47 minutes since you last successfully posted a comment
So I've been writing this COM-server for windows, which you can use to add equations to wherever (say, Word). basically 2 modes of operations:
(a) Click a toolbar button and an editbox opens where you type your expression in a simple infix notation (e.g. @integ(-#inf#,#inf#, x^(@root(y)), y) and it's inserted as a rendered equation
(b) Type the infix notation expression in your word document, select the text and click a toolbar button to convert to a rendered equation.
I haven't touched it in a long while but it's quite in a working shape, easily maintained etc.
Several people have used it and were quite happy with it.
I didn't want to go into the trouble of releasing and maintaining the source because I don't know how useful this would be for people, but if there's enough interest expressed in replies here I'll be more than happy to do so.
I'll monitor this thread over the weekend and post the location...
It works for me.
type them on your laptop when you arrive home.
I've done it myself using the equation editor in openoffice writer (which is way better than the one in MS office). It is very powerful and with a bit of training you can be really fast (some times I'm faster then my friends who are writing by hand).
I have to agree. Last semester my math prof hired me to take notes in his Cal 3 class and I used Scientific Notebook. Once I learned all the keyboard shortcuts I was able to keep up in realtime. It is very intuitive and makes a lot of sense.

I want a list of atrocities done in your name - Recoil
Though it may not be quite as easy to read initially, a prefix or postfix notated expression would work well on a (probably wrapped) line, and could therefore be good for simple text editors (which is what I use for taking notes). People experienced with this (LISPers?) would be better suited than I am to say if this would work well.
The problem of course if bad handwriting. If my handwriting was like Dijkstra's, I would definitely write a lot... But most CS students have bad handwriting... so we hate to write. And we type faster on a computer too. So if we just could type formulas as fast as text...
I'm not insane! My mother had me tested.
Emacs, latex, macros and a bit of preparation. Obviously yo DO 10-finger type. .\i_{-\I}^\I e^{-x}dx
is NOT that hard on a US keyboard.
I used for years Mathematica. I tried MathCAD, Maple, Matlab, LyX, LaTeX, Microsoft Equation Editor, and the new ecuation editor in MS Word 2007 .... and nothing beats Mathematica in terms of writing speed, and even overall rendering performance.
I hated MathCAD that it was all about clicking on toolbars, promoted the "clicking" game, lol. It sucked.
Other editors sucked for being too terse. For example, LaTeX is too terse, you have to write too much, and there's no nice editor with live preview. LyX wasn't that nice.
I used Mathematica all through high-school, together with The Geometer's Sketchpad for all the dynamic euclidean geometry needs. Mathematica has unparalleled number of keyboard shortcuts, command aliases which allow you to insert any weird character and formula in-place really fast. One of my primary concerns was also rendering and performance: I kept a one-year long document of home works and written notes which amounted tens or hundreds of pages. Mathematica had no issues while others barely worked. Rendering was important because following very hard equations in LaTeX form would suck hard - when it's all rendered live it's all much easier to read and follow, and thus calculate.
I should note that Mathematica was great that it was available for Linux and Windows. Sketchpad only for Windows and Mac, but with WINE it ran fine on Linux as well.
Ultimately, Mathematica proved to be a good tool for math learning as well. I used its facilities for solving various mathematical problems, to check my homeworks, to learn.
...Like a normal person and stop being such a pretentious bastard showing off your Macbook Pro.
Try the Aiptek MyNote. Awesome piece of kit and you don't even need the computer in order to take your notes.
I studied engineering for quite a while and I used to use MathCAD (on WinXP) for typing all kinds of equations. It's a program for doing algebra (so it also does the whole calculating stuff for you). I was a lot faster with typing than all my friends were handwriting. There ist one tricky part thou: MathCAD has its own syntax, which is quite different from LaTeX's. More here (http://en.wikipedia.org/wiki/Mathcad) and here (http://www.ptc.com/products/mathcad/). If I remember right, my university gave it away with some kind of student's license, so I guess it's easily available for you, too.
For taking notes in higher math classes, you've really got to use a pencil and paper. Nothing else is going to let you write complex math notation fast enough, especially when you start getting into modern algebra and using symbols you've never seen on a computer before. (Most of them are technically available in Unicode, but you don't have time to go hunting for obscure codepoints during class.)
Write on paper with a pencil, and then scan your notes onto the computer after class. File the paper copies in a folder until the next time you update your backups; then you can toss them.
Cut that out, or I will ship you to Norilsk in a box.
Take photos of professor blackboard
...without much problems, thanks to an eight-level keyboard and less-then-you-think macros. Also I can write down most commutative diagram live. Take a look at this page where I explain my method.
Additional pro is that the tex source are almost visually intelligible without compiling.
Anything worth writing is worth writing once. If someone already wrote it in the text book. Then that is good enough for me.
I have to disagree with you there. Personally when I was at university (I read mathematics) I found there was a huge amount of value to be had in the physical act of copying out the equations and text from the blackboard (either by hand or by computer but generally by hand). It forces your brain to slow down, concentrate properly and take in what's being said for one (which is no mean feat); for another, a lot of people (me included) find that the very act of copying out word-for-word helps them commit the concepts to memory.
If the equations are on a blackboard, whiteboard, or projector screen, try using a digital camera... After all, a picture is worth a thousand words.
indians...dont u have indians in ur class? i m sure they write down every word...just use that dude..!
rather..as everyone is saying..get simple and old....use pencil..not even pen..too much dependancy on ink..just use pencil and paper.
Why don't you just write the equations down in a notebook, then put a number into your typed notes? You can LaTeXify the equations (or embed them in whatever way you choose) after class.
-- There are 10 types of people in the world: Those who understand binary, And those who don't.
it's called the Book
At many advanced institutes of higher learning, especially at the graduate level, is it not uncommon for there to be NO BOOK. The professor's weekly scrawlings on the blackboard are all you get.
If you want speed of note-taking and your computer just doesn't hack it - then it's not the tool for the job. Paper and pencil is. Take your notes with that, then transcribe them to the computer at your convenience. Really, have we gone so far that we're beyond actually writing by pencil anymore?
As another possible alternative, something like Canson's Papershow (http://www.papershow.com) might be worth trying: Doesn't have a Mac version yet, but is a nice way to actually write things, and have them saved to the comuter.
I think I got just the thing. It's called Microsoft Courier..and hopefully it will be available first quarter next year. http://gizmodo.com/5369493/leaked-courier-video-shows-how-well-actually-use-it

and then type it up in latex at home. I find typing on a computer in "live" class setting is distracting and takes so much away from active mental participation that aids in learning. You are so much better off taking notes and asking questions while the material is being presented.
If you really care about having a readable, electronic archive of your lecture notes, then type it up in LaTeX later on in the evenings if you still have energy and time left.
As the island of our knowledge grows, so does the shore of our ignorance.
My suggestion will be pencil and paper... mark in ur soft copy notes the equation # and write the actual equation on ur notebook (paper based)... u can do the post processing of getting the eqn into ur soft copy notes...
While I am still a fervent user of the classical notepad (not the software kind) one has to acknowledge that the abilities to share, copy, backup, search, edit a document are quite good to have.

Pen and Paper? seems best.
But to stay relevant:
A scanner? a handheld one would probly do.
A A6 graphics tablet?
Or the expensive option, one of those digital pens? that stores your scribbles in the memory for transfering later?
----- I refuse to have an argument with an unarmed person
While I don't recall exactly which methods for inputting equations it supports, I do remember that Maple (http://www.maplesoft.com) is a great tool for working with mathematics.
If you use LaTeX, there are some programs that define keyboard shortcut packages that that vastly cut down the typing required. Using them takes a little bit of getting used to, but once you do, they may be exactly what you're looking for.
If you use Emacs, my favorite is Ultra-TeX: ..." to produce the Greek letters " \alpha, \beta, \gamma", gives you a opening and closing braces automatically when you type "_" or "^" and puts your cursor in the right place, along with many more little tweaks that save a lot of time.
http://www.math.washington.edu/~palmieri/ultratex.php.
It does a bunch of things that speed up LaTeXing. For example, when you type a dollar sign, it automatically inserts a matching one. If you type '$' again, it cycles through the different equation environments (equation, align, etc.) until you get the one you want. It also dynamically completes commands once you've typed enough to uniquely specify them, lets you type " `a `b `g
If you're not an Emacs user but use UNIX or Mac OS X, another good alternative is:
http://www.cds.caltech.edu/~fastex/.
(Or, if you use Mac OS X and don't know how to work Emacs, you might want to try Aquamacs (http://aquamacs.org/), which is an Emacs implementation for Mac OS X that adds a standard Mac OS interface to Emacs and really shortens the learning curve. Then you can use Ultra-TeX without having to learn Emacs at the same time.)
Microsoft Graph or Equation Editor works well once you get over the fact that's it's MS.
Or what about Apple's Grapher?
They all make typing in equations easy.
A tablet PC and Microsoft OneNote is serving me well in the exact same situation as the poster.

OK, I'm too late to this thread and this probably won't get seen, but I'll jump in here anyway.
Your thread is one of many that I have seen that says, "Just use pen and paper, it's too hard to use computers to write maths!"
What a bunch of Luddites!
Yes, we all get that it is very hard to write math notes on a computer - that was the point of the original poster's question - how to do this better and more efficiently!
For all of my non-science classes, I found using a computer to take notes to be FANTASTIC! Why? I can touch-type. So I can take notes without ever taking my eyes off of the professor. I can also type faster than I can write. So I'm faster at taking notes. My type-written notes are also far more legible than my handwriting. My electronic notes are more space-efficient, and are electronically searchable. I can also share them with anyone anywhere in the world instantly.
The benefits for english-language note taking on a computer are, for me, absolutely indisputable.
If it wasn't so fucking hard to write mathematical and/or scientific and/or engineering symbols on a computer, we could enjoy the same benefits there!
So the answer to the question is NOT, "use a pencil", but rather to find a more efficient way to to it.
A work that expires before its copyright never enters the public domain and thus enjoys eternal copyright protection.
Well, I now know that most of the posters on slashdot encourage the use of a pen and paper for various reasons.
Let me explain why copying the notes feverishly isn't the best idea.
Yes, a lot of people remember things they have written down.
However, I would argue that actually understanding the equation/notes you are writing down is far more important than memorizing it.
I say this as someone with a degree in mathematics and engineering.
It really depends on the course and the person if you want to transcribe everything or not.
I knew students who would write down the notes, go home and copy them, and then do it again.
I also knew a student who never took any notes. He used to say, "the information is in the book, I am trying to understand the lecture". That student is now a professor of Electrical Engineering at a major university.
I am not going to question why the original poster wants to do everything on a computer, I will just help him.
Mathcad is exceptionally clean and simple for "writing" math. It is the best solution I have seen. Unfortunately, it is designed for active math solutions...so it may not be the best solution. I would give it a try though. I know that for engineering classes it was one of the most helpful programs I ever used.
As far as "higher level math courses", it depends on what you actually mean. My higher level math courses were all theory courses.
If you are having problems with note transcription in number theory, I would recommend learning math proof shorthand rather than trying to use LaTex. Most math shorthand uses Greek symbols, so you can learn the shortcut to them
If your "higher level math courses" are calculus. I think most of the recommendations would be ideal.
However, I might recommend a different course. Typically a professor will tell you what he will be discussing next lecture. It might be easier to setup your equations ahead of time. They are almost always available in the book. You could then record your notes for any equations with the main equation.
It would still require the use of a math symbol software, but you could make sure that the important equations were already very cleanly entered.
To recap:
Number Theory: Learn symbol shorthand
Calculus: Can't get much better than LaTex derivatives
Engineering/Physics: Try Mathcad. It is designed to give you answers, but it allows you to actively play with equations and input numbers to get a feel for the math.
I still have two enormous notebooks full of math notes from the classes I took...and I finished school some 13 years ago. Remind me why you need this information on the laptop, again?
What annoys you about onenote? The only thing that really pisses me off is that regardless of what amount of proc I tell it to use at which times, it tends to lock up solid for a few seconds to 20 seconds or so every once in a while. Especially when I paste an image into it (I have ocr of images disabled supposedly) or when I use the pen for the first time since a hibernate (did it forget I had a pen?). I can live with both of those. For my mode of thought a tablet with onenote is just too handy to give up. Google needs to come up with a replacement. I'd like to have google notes on my phone and tablet so I can easily send lists and stuff to my phone from the tablet and take notes impromptu then sync them back to my tablet. (I do have onenote mobile, but I don't want to type. I think better when I write and draw images for some reason.)
During pre-historic times, I would just copy the instructors chalkboard scrawl into my (paper) notebook. It was fast and efficient. Why re-invent the process with purpose built software. Use a touch screen netbook (i.e. Dell Latitude 2100) -- Just open a graphics editor and draw the equation in free hand on the touch screen.
Wacom has a few cheap low end tablets that are not marketed as graphics-tools and if you want to go really cheap there's always the tablets made by Trust.
But if you are going to use a tablet to make your notes you will probably find that it is easier, faster and result in higher quality to use a good pen, a blank (no lines or grid) paper and then scan it. That also has the benefit that you don't have to set up your computer during lecture.
/.Mattsson - My native language is not English, so please don't whine over linguistic errors. (That's lame anyway...)
I'm a math professor who actually uses the SmartBoard in my room, so my students don't have this problem...
Use the OpenOffice.org Math program. That allows you to enter equations using your laptop. It works on Windows, Mac OS X, and Linux. You can type in text notes around the equations.
... use paper and pencil. But everyone beat me to it.
Seriously, you don't have to lug around any equipment, it is cheap, it is fast, it doesn't require a battery, the operating system is your brain ...
Good luck.
I am a professor of engineering, and the way I solved this problem for my students was to write software that allows me to process photos of the whiteboard very quickly (a minute or two per day). It automatically puts them on the web for the students. They can browse them at: http://people.wallawalla.edu/~Rob.Frohne/ClassNotes/ and they can print a pdf document of them as well from the web site. Lately I've included an MP3 recording of the lecture as well, so that they can hear it again as necessary. The processing software is called Save My Whiteboard and is available under GPL3 here: http://people.wallawalla.edu/~rob.frohne/SaveMyWhiteboard/index.html The php code for the web pages is available under GPL too if anyone really wants it.

If you are using a Mac, I recommend grapher. Type your equation in the input field at the top and then transfer into TextEdit via the clipboard.
Grapher is quite capable. It can pretty much produce arbitrary mathematical equations.
If you're emacs user, you can combine latex (with defined shortcuts for often used equations) and auto completion mode in emacs, which will complete anything you type.
Pen/Pencil and Paper for serious equations will beat any I/O interface anyday. Even tablet recognition pales in comparison, though direct tablet drawing might come a close second. I do this for all the notes I need to take, and as an added benefit, I'm forced to review my notes if I want to enter them onto my computer when I have more time. Plus, you can absorb the lessons better if you're not focused on the details of entering long equations into your computer.
The unexamined life is not worth living
I simply cannot keep up when I write notes by hand -- but I type very quickly. I too have had trouble with equations, and my solution works for me, but isn't the best. Here's my approach, fwiw.
Type notes on my Eee, it has a 7-8 hr (actual) battery, and a relatively quiet keyboard, so as not to be a distraction. I can watch the instructor and the board while typing, unlike handwriting. Using emacs under windows at the moment (better battery life pending some driver updates for linux)
I keep a notepad for any graphs, and I just number any figures I draw. I switch between keyboard and pen as rarely as possible.
Equations are important -- I'm a math major now! For some classes, equations will come as fast as the instructor can scrawl them on the board. I write in an abbreviated shorthand, basically supremely-lazy latex. I neglect anything that could be implicit, and write, for example, omg and Omg instead of \omega and \Omega. I only started a little while back, and I still adjust my abbreviations as I go. That means it's not really parsable yet, but I am doing a good job of figuring out the minimum number of key presses to say what I need to say. After writing it for a while, at least it's easy to read (much like latex, you'll start to see it without needing to render it before long).
I like the mention of cameras. I've started doing that for meetings with my advisor, just using my iPhone to capture the whiteboard after we've gone back and forth on a few ideas.
I've been through N (where N is large) years of school, but only in this last year have I switched to typing. I have a great deal of trouble with handwritten anything (random word and letter transpositions everywhere, HORRIBLE if you're trying to write a mathematical theorem). Switching to typed notes has been one of the best decisions I ever made wrt taking classes.
-- That tickles!
Get an iPod Touch (or an iPhone, if you need a phone); install any one of the drawing programs on it from a whiteboard to AutoCAD's awesome layer-based drawing system, and use that.
The touchscreen interface allows unrestricted freedom of drawing and 1:1 relationship between your drawing motion and the drawing that you can't get with a tablet; the work-spaces of some of the software are quite large (and layers are useful here); and the software is inexpensive. The icing on the cake is that there are tons of other useful apps as well.
The downside, of course, is the cost of the iPod. But other than that, it's the perfect solution. If you already have one, then it's a slam-dunk: a few bucks (like, one or two... or maybe $20 for the autoCAD one if I recall, not sure), and you're golden.
I've fallen off your lawn, and I can't get up.
In my day we used a pencil and paper. Always use the correct tool for the job - for class notes a computer isn't one of them.
Except when I was feeling adventurous and would use the Psion Series 5 and scrawl equations and diagrams on the screen, type things in with that nice keyboard and print out to the HP printer via IRDA. One copy to hand in, one for future reference and one donated to the cause of plagiarism. But invariably I was glad to return to pencil and paper.
Failing that another vote for LyX as a way of doing LaTeX without spending ages typing in all that markup nonsense and missing half your notes (and most of your attention)
I'm in a similar situation as you. I am taking graduate-level statistics courses and much prefer digital notes. I work on a MacBook Pro (I also use a virtual machine for my windows needs). First, I'll admit that I haven't used Lyx's equation editor. I tried OpenOffice's and was thoroughly unimpressed, but maybe I didn't give it enough time. So this response doesn't necessarily discount those possibilities, but simply extols Word 2007's "new" equation editor as a very productive tool for taking realtime notes in a symbols-intensive class.
The "new" equation editor in Word 2007 lets you edit equations right in the document (it's no longer a plug-in). To start an equation I simply hit alt-enter. Once in the equation editor, I just type equations almost as if they were LaTeX. It accepts most of LaTeX's math symbols, e.g. \sum \alpha \int \infty \prod. I've almost never come across a symbol I needed but Word didn't have (most recent one that I was surprised Word had: \biguplus), and you can even easily add your own for those that are missing.
There are some differences from LaTeX that you will have to learn, mostly for the better! For instance, you never have to do \left( or left\{ just plain ole' parenthesis, braces, brackets, etc and by default they autoscale (you can force it to not). And for fractions no need for \frac{num}{denom} just (num)/(denom). For these reasons and others, Word's equation editor generally requires much less typing than LaTeX's and you seldom have to use the mouse! And since it is WYSIWYG, when you make a mistake in your typing, you just click on (or navigate with the keyboard to) the actual mistake--no sorting through compiler output and very verbose markup to figure out where things went wrong. The instantaneous feedback is a huge productivity boost. You can even edit the markup for the equation directly (you'll probably never have to do this, and if you do, it is harder than editing LaTeX since every "command" gets converted to single unicode characters; but again, you'll never have to do this). Of course, if you don't know a command, you can easily find it in the GUI menu--but this will put you behind in your note taking. The Lyx or OpenOffice solutions may offer similar benefits.
Bottom line: I'm able to take notes in realtime in very math intense statistics course that utilize a bunch of strange symbols. Something I'd never be able to do using, say, Kile as a LaTeX editor.
As for battery life etc., I must admit that I use remote desktop to connect to my windows desktop so battery life is hardly affected. I rarely experience latency problems, either. I'm thinking of trying to run Office 2010 in VMWare Fusion to see how the battery holds up, but I suspect it will cut my battery life almost in half, so I imagine I'll stick to the remote desktop solution.
That said, I've generally found the paper/pencil option much better. I did try the Mathcad route for awhile, but in most math/physics/science classes, there's just too much jumping around. E.g. Oh - and this connects back to that... etc. It's just really hard to circle something and draw an arrow back to a previous note on the page with software.
JDB
I've written a simple equation editor which behaves as a COM server, i.e. it can be used in place of MS equation writer in Word or any other COM client.
It's based on a simple expression syntax (e.g., @sum(i=0, #inf#, 1/i)) to specify expressions.
There's also a word addon that will let you select text in word and convert it to an equation.
A couple of friends used it for a while and it worked for them; I never published it because I wasn't sure anyone would care.
However, reply to me if you think I should publish it and if I see enough interest -- I'll go ahead (probably even open source it)
I have the same lockup problem, only much too often. And it happens most often when I'm converting ink to text, which makes that feature almost useless.
There are too many bad features to list. The one that really gets my goat is that a lot of the formatting feature, such as tables and bullet lists, are just not usable if you don't have a keyboard!
Any engineer worth his (or her) salt knows that RPN is the way to numerically solve an equation. The algebraic entry using parentheses is for suckers. So that got me thinking... why not use RPN for equation entry? As usual, I'm late to the game. There is a Mac app here. Sorry, the site is Japanese...
There is a web app here. Seems to work well. You can make pretty big equations quickly, and the result is in tex.

As I understand it, cutting distance from the Kessel Run refers to a shortcut that only select craft can actually make use of. So watch your pedantry lest someone out-pedant you.
I agree that a year ago that was certainly the case but you need to update your desktop software. You can delete pages now. However the software is still not as polished as I would like but it does have the minimal basic functionality now.
Take a moment to re-think this desire to type-set class notes... Why worry so much about electronic class note-taking in a science, engineering, or mathematics course? Why not spend the best of your energies solving difficult problems and preparing for the exams? Unlike arts electives, probelm solving is the real meat of these courses. You're rarely asked to reproduce neatly type-set class notes on an exam! But just think of how much more capable (on an exam or a real-life engineering analysis situation on-the-job) you will be if you spend more time solving extra problems. Try this: just take good hand-written notes (that can be digitally scanned later for portability or topic-specifc filing) or read and & annotate PDF's provided by the more enlightened professors. Then when problem-solving make detailed notes of your solutions using electronic entry like LyX or MathCAD. MathCAD or similiar software tools add value to the process by eliminating the requirement of endlessly entering numbers into a calculator during your problem analysis work (you can always just practice the use of a calculator just before a test for speed-finger-muscle-memory - but why waste the whole semester on that tedium?). Having very good "problem-solving notes" is like an "applied summary" of nearly everything important you need to know to do well on a science, engineering, or mathematics exam. It's also a good reference for down the road when you revisit the material for further applications. Spend 20% of your time reading your class notes as an introduction to the material (or review before a test), but spend 150% of your time banging out well-documented and neatly organized problem solutions. Then see how much time you have left over at the end of your course to type-set your class-notes! Probably none if you have a full course load; and you'll be happy that you instead are well-prepared for your final exams :o)
Cheers and Enjoy your Learning Adventure!
Amazed nobody's suggested the obvious thing to do: Skip the lecture, hit the bar, play pool, flirt with the attractive students of your preferred sex and get a copy of the lecture notes from someone else.
University is where you get an education, so skip the lectures and get one.
The equations go in your head, not in your computer.
Get handwriting recognition software/hardware. Then write the equation in.
For $14.95 you can get a stylus that will allow you to draw on your macbook trackpad thus turning it into a small tablet (see http://www.tenonedesign.com/sketch.php). Combined with the right software this should work well for entering equations, sketches, etc. It's cheap and requires just a pen that you can shove into your pencil case.
Well, use an iPhone.... "There's an app for that!" then sync it with your MBP via bluetooth and paste. Wala!
I use paper. It works great.
If you need, you can scan it later. Technology is wonderful, but it should help you, not get in your way. Use it correctly.
I am baffled by the number of people saying, "Just use pen and paper that's the best way for me." How is that an answer to the question? "We don't need none of that there change stuff. If dinosaurs were good enough for Jesus to ride to pre-school then they're good enough for those people younger than me."
It sounds to me like a simple keyboard map would solve a lot of your problems. Map your F-keys (function) to various...functions. I can think of a couple of ways to do it off the top of my head, but a customized software solution shouldn't be too incredibly hard either. Just requires a text entry field, some math-specific formatting of the text, and the ability to hold down shift or control or iKey or something to define when you're typing 'special' pre/custom-defined characters.

Use a fucking pencil. Name one advantage that note-taking on a computer has over pencil and paper for the average (read: you) student.
I've wanted to take digital notes for myself (mostly math) for a long time, but have had a hard time finding something relatively cheap and portable. I'm optimistic that the Touchbook (http://www.alwaysinnovating.com/touchbook/) will fulfill my needs. I've preordered, and expect mine any day now.
1) Learn Emacs
2) Learn the AucTeX shortcuts
3) AucTeX has a mode called latex-math-mode. This gives you quick shortcuts for entering the Greek letters and some common set notation
4) Create your own Emacs macros
5) Create your own LaTeX commands
For example:
\newcommand\probspace{(\Omega, \mathcal{F}, \mathbb{P})}
will be helpful if you are taking notes in probability.
I have used this combination of tools and I can take notes in real-time in most math classes.
I went through an Econ MA program with the same problem, and even bought a tablet pc and tried to use OneNote to do it. In the end, I found the fastest thing was OpenOffice's formula entry system, Math. The commands are very intuitive, ie. x over y for x/y, and once I learned them, I could type faster than I wrote anyway. It does have the disadvantage of not holding alot of equations at once (at least 2.0 did), and integrating your Write documents is a pain, but it was still the best solution for me. I would usually switch between Write and Math, and just make a note in writer to insert the equation here... or, if it was something short, type the math commands right into writer and then convert it later. The big plus is that, once it is in, it is in a computer-readable form, so there is no "going back" later.
I have a friend at work that uses a tablet and Microsoft OneNote, as sort of virtual ink on canvas. It's secret is that you can scribble anything you wish with the stylus, then fill in with keypad later for the parts it doesn't understand (from MS Word). I think the notepad costs him about US$800 or so, and he uploads to the server via bluetooth so we can all see the notes (meetings, scrums, etc.). He loves it, and it sounds like what you need with essentially NO learning curve. Then again, nothing is free...
The common usage assumes effort on the y-axis and progress on the x-axis, so a steep learning curve is one in which a lot of effort is required to make little progress. This is conveniently intuitive to the notion of a hill to climb.

Get a digital pen. You'll be able to write the equations on paper and get the muscle memory boost from actually writing them down, and be able to sync the contents to a computer. Other pros include the fact that you won't even need to have the computer on as the pen has it's own memory. The con is that you have to buy special patterned notebooks and the pen is a bit large.
Logitech has a $150 one that is pretty good: http://www.amazon.com/Logitech-io-Personal-Digital-Pen/dp/B00006JP23
Yeah, I like to hate Microsoft just like everyone else but I'm still a Windows user (Mostly for the games compatibility). And I have still not seen a better solution for writing down lecture notes than the Word/MathType combination. Yes, they are both proprietary software (Which I get free through the university. :) ) but I've been using them for the past two years and I'm faster than the lecturer. Yes, I write as fast as the lecturer speaks and faster than he/she can write themselves.
:)
MathType is quite comprehensive, I don't even use half of what it offers myself, and the whole catch is shortcut keys configuration. You can set up combinations for 'macro' equations (Like Limits) and with two presses of a button call down a set that will take other students a few seconds to put down.
The only problem I found with it so far is a symbol or two it doesn't have (Like the under-tilde not-equal sign) and you have to build yourself and the fact that when you write integrals, the lecturer does the limits first but you have to add them last.
For sketches, graphs and diagrams there is no comfortable solution I found. I either draw them in Word shapes with a pen-mouse, plot the graphs with Mathematica (Best analytical math tool I found) and copy over or just photograph the board and paste the image into my document.
Trust me, I've been doing it for two years.

Let us meet again in "Less Interesting Times"
Note taking, for me, was to summarize what the teacher said, in MY words so that I could understand it later.
Well, in a calculus class you will, at some point want to write something like "We know that f(x) = e^x is a monotonically increasing function". Since you're taking notes, "monotonically increasing" will probably be rendered "mon. inc." in notes, but f(x) = e^x can't be compressed further.
I can't speak for anyone else here, but I think linux is garbage, and I would be *embarrassed* if someone even knew I was using it.
Mathcad has a very simple pallet based equation creation system. You could probably find an old copy very cheap.
Org-Mode for Emacs has pretty good LaTeX support. For one, it identifies equations automatically, so you can dispense with the $ signs. It also converts the formula to an image in the buffer, so you can see the actual math instead of markup. With CD-LATEX, it even offers tab completion of LaTeX templates.
Combined with Org-mode's export capabilities and hierarchial ordering, it's a pretty good tool to take notes with. I've handled a couple of physics classes with it, although I eventually reverted to pen and paper because I kept getting distracted.
