TI Launches Three New Graphing Calculators

Posted by michael on from the if-you-can't-make-it-good,-make-it-pretty dept.

confusedneutrino writes "Texas Instruments has announced 3 new graphing calculators to be available later this year. The TI-84 Plus and TI-84 Plus Silver Edition will be available this spring and are essentially the TI-83 Plus/SE, respectively, in a new case and with USB support. (The TI-84 Plus does sport a 15 MHz processor, compared to the TI-83 Plus' 6 MHz, though.) The TI-89 Titanium will be available in the summer and features 3x the available ROM of the 'old' TI-89 and will also have USB capability. Looks to me like a Voyage 200 minus QWERTY. I personally don't feel an inclination to upgrade at all..."

  1. Graphic Calculators ruining math in schools. by WordUpCousin · · Score: 0, Troll

    Im 24, and during the time i was in High school, was when Graphing calculators started getting popular. This is how I'd make sure i got 100's on all my tests.

    For derivatives, I'd map out my answer vs what the graphing calculator said: example.
    Y1=3x^2+5x (the problem)
    Y2=6x+5 (my answer)
    Y3=Y1' (the answer)

    Another solid use of this was in trig, cuz i was never good a remembering the sin,cos,cot conversions. So, the problem might have been: "Simplify sec(x)cot(x)+sin(x)cot(x)"
    a. tan(x)+cos(x)
    b. tan(x)/cos(x) + 1
    c. ... d. ...
    ... I'd just plug in a random non-obvious degree value for X to find the solution.

    Nothing more thrilling than graphing calculators! where's that snooze button?
