Calculators Graphing Calculator: - TI84 vs Casio CFX9850GC+

  1. Dec 29, 2007 #1
    I'm about to buy a graphing calculator, and I don't know whether to get the Texas Instruments TI-84 (Silver Edition), or the Casio CFX9850GC+ (which has the added frivolity of a colour screen).

    I can't get the TI-89, because it has algebra software built in, and so I'm not allowed to use it in an exam...

    Your opinions, please?

    You are right about the TI-89, it actually has a software built-in. You might opt for TI-84.
    Also, there might be another constraint as the main purpose for your consideration, eg you might think what after the buy, it costs pretty high, if you can find some relatives to help you the cost then it'll be fine also for you, won't it ? I think its fine. But you need to clearify why your hesitation all up.

    Well, both calculators are about the same price - the cost isn't that much of an issue. I'm just unsure which one to get - which one's the most powerful, the easiest to learn to use, the most versatile...

    I hear Ti's are easy to use. I versatility would more than likely go to the Ti because there are so many programs you can use for it.

    Sorry I didn't understand ,
    easy to use due to familiarity
    most calcaultor are made easy for students to use
    if the calculators are for complex computation then choose the more functioality since the simple one would completely refuse under whatever circumstances
    also it takes TOO long for you to just look and hesitate, if you are not decisive, then ask someone in your class who has more experience to pick one for you.

    Jekertee had the best advice, ask someone in your class.

    I personally like the TI-84, but mainly because I'm familiar with using it and not the Casio brands.

    The color of the screen to me doesn't matter that much just so long as the calculator is robust and has full functionality.

    I just read that about your not being able to have algebra software built in.

    But for graphing capability I bought a TI-92 around 10 years ago. They made an upgrade: http://en.wikipedia.org/wiki/TI-92_series
