Ask Slashdot: Cheap Second Calculators For Tests?
Rich0 writes "I own an HP 48 calculator that I'm quite content with, but soon I'll need to take a certification exam where this calculator will not be welcome. I'm sure this is a common problem for those who own higher-end calculators. Sure, I could just buy a random $15 calculator with a few trig functions, but I was wondering who makes the best moderately-priced calculators for somebody who already has and appreciates a programmable calculator and just needs something simple. Bonus points if the calculator can handle polar vector arithmetic and unit conversions, but it has to be simple enough that virtually any exam would accept its use."
I believe the TI-36X Pro would probably do what you are looking for. It is approved for use on Professional Engineer tests, from what I have read.
I have a TI-36X Pro for basically the same reasons you outlined. It's quite affordable too, and if you're in the US (I'm not) then it is really easy to find.
Check out the NCEES Calculator Policy.
I had a non-programmable calculator in college but it died and I didn't need a calculator at work. I bought a TI-30Xa for when I took the state professional engineering exam. I am still using this calculator as an engineering professor. Plenty of capability.
step 1: buy a retarded large button lcd calculator with w huge screen and fixed digits (you know, 0-9, ., +, *, /, -)
step 2: replace the buttons with joysticks
step 3: replace the screen with something around 300dpi
step 4: put in an arm processor and bring up linux
step 5: add wireless networking
step 6: swap out the aa batteries with lithium
step 7: develop a chorded keyboard input on the now 9 position keys
step 8: write an emulator to pretend to be the original calculator
step 9: profit
There is a jerk just like you at my job. I'll ask coworkers for their opinion on a particular tool, and he has to but in and say, "You can just Google for the tool and find hundreds of them for sale." I don't ask my coworkers because I need a list of names, I ask them because I want their opinion, and usually specific to the type of work we do. Part of "growth" is just not knowing what is the most popular choice, but knowing the criteria people use when selecting a tool. And just like that jerk coworker, guys like you will complain how such requests for opinion and discussion waste your time by making you do other people's work for them, yet you have no problem spending way more time whining about wasting time than you would with actually moving on and doing whatever makes your time so important.
You want people to speak up, and not sugar coat things for the purpose of "inoffensiveness"? Well, the did, by down modding such garbage. You want to value honest expression over phony appearance, yet bitch when it turns out people disagree with you.
Thanks. I can obviously read Amazon reviews and such. However, I felt that the /. community probably had tastes more similar to my own, vs a bunch of kids taking algebra in high school/etc.
Yes they can, but is that a problem?
When I was in school, my math classes required the use of a graphing calculator (it was a private school, so they required students get either a TI-81 or TI-85). I discovered the TI Basic features and thought that I could ensure myself high test scores by simply writing programs that could solve all the types of problems that would be on the test--this wasn't illegal, provided we wrote our own programs. The first few times I did this, I fully intended to use them during the test, but I found that it was usually just quicker to solve the problem myself, though I'd occasionally check my answer using my program. It was basically impossible for me to instruct the calculator on how to solve the problem without fully learning how to do it myself. And it became clear to me that simply writing a program was the best method for me to study for tests. Prior to that, I would cram before the test and sometimes it would be sufficient and sometimes it wouldn't. But in writing the program, I could very easily tell when I was done studying and it took far less time than the traditional method. And, unlike cramming, programming was fun!
From the interest that I gained in programming TI Basic, I decided to take an intro to CS class the summer before my freshman year of college. That led to my majoring in CS and the fulfilling, enjoyable and well-paid profession that I've had for the past ~15 years.
I'm very grateful that my math teachers in high school didn't see things they way that you do.
