TI - 89 vs. TI - 83

LegendoftheWarriorLegendoftheWarrior 338 replies33 threadsRegistered User Member
At my school, we didn't really use a whole lot of graphing calculators, but we did use TI - 83's once in a while. We used that for Intermediate Calculus last year, but we performed REALLY simple problems on the calculator. With that said, it's obvious that I don't have much experience with graphing calculators. I guess my question to you is: Should I purchase a TI-89 and learn how to use it? (I have a feeling that it may be hard to use.) Or, should I just purchase a TI - 83 and go with it? Any replies are appreciated. Thanks!

    hmmm i don't recommend graphing calculators, in fact i don't recommend calculators at all, but sometimes they are needed, so just get like a $5 calculator that can do sine, cosine, tan, log, ln and that's all you need i think, graphing calculators are sometimes limited too when you go to college, b/c some colleges don't allow TI-89/graphing calcs in general, so you should get used to that $5 calculator now :)
    that's what i did :P

    I see, Newbyreborn.

    But from what I've been hearing, lots of people buy the TI - 89 calculator so that they could insert programs and formulas within the calculator to ensure a high score.

    A TI-89 is very helpful for the "old' Math-IIC that is now called Math Level II. Students who master the use of the TI-89 have a distinct advantage. However, you could do as well with a TI-83.

    For the SAT, a simple calculator will suffice but won't really help you much. It will slow you down for some problems and be of marginal help for other problems.

    There is no faster calculator for the SAT REasoning Test than the one between your two ears. :)

    Sorry guys, I should've mentioned earlier that the TI - 83 or TI - 89 I'm planning to purchase is for the Math IIC test.

    I'd say the TI-83 is sufficient for the Math IIc test. I used one, and got a 770. For the SAT, any calculator will do.

    Thanks, somebodynew. Just being curious here, did you use Barron's prep book as well?

    TI-83. TI-89 would be good for storing games. =]

    So what additional functions make the TI-89 a "better" caculator? I don't know if it's just me, but a lot of CCers use the TI-89 and kept getting 800's. That's why I'm tempted to purchase one, but yet I'm relatively new to graphing calculators.

    I wouldn't suggest jumping right into getting a TI-89 if you are relatively new to graphing calculators. It is more difficult to use and get used to than the TI-83+.

    TI-89s are easy to use. It is easier to use and get used to than the TI-83+. It is my first and only graphing calculator. Just the history function is worth getting the TI-89 rather than the TI-83+.

    Haha, I'm getting conflicting opinions here.

    Hecatonchires, you're saying that the TI-89 is a piece of cake. In your opinion, would it be easy for someone like me who's not quite used to graphing calculators yet? I really don't want to waste time trying to master a device for a test if I can get a 800 by using an "easier" calculator.

    aaaah... to Legend- don't buy the 89 just for the SATII.
    The point of most of the questions on those exams isn't to make you solve complicated equations anyway. If you're used to the 83, even a little bit, it's not worth trying the 89. The simpler math functions are easy enough to figure out, but honestly it's not worth your time to use the solve functions and look up formulas on the 89... better to spend the time to make sure you're approaching the problem correctly. (Besides, those things can be done on the 83 anyway-the real advantage to the 89 is solving Calc problems.)
    (and of course for reference, I used an 83 and did well... but the 89 was brand new back then :))

    I have a ti-89. You should get one. It is not hard to use, and if you can't figure it out, it comes with a manual.

    I have a TI-89 that I asked for as a gift during my senior year of high school (I'm not weird, but for my planned major and career it seemed an appropriate gift to ask for). I really like it. One of the distinct advantages for math, although not for the SATs is that the 89 can graph 3-D. I really enjoy using the calculator, this year it was mostly used for my physics class and I used it some for a calculus review that I went to. I highly recommend the TI-89, and I've switched over from the TI-83. The TI-89 is pretty easy to use, but you do have to get used to it.

    Thank you. I'm sort of leaning towards getting a TI-89 here. Do you think that it would take a month for an average person to learn how to master the TI-89 and get used to it? Also, is the TI-89 a lot different from the TI-83? My whole class will be using the TI-83 next year in Calculus, and I just don't want to be the odd ball with different functions and all. :p

    I prefer the TI-89 because of the Computer Algebra System ("solve" is my best friend) and the "pretty print" feature (displays entries and answers the way you'd write them, and in exact form if you prefer). I find that the CAS and pretty print tend to prevent a lot of stupid mistakes, as well as allowing you to solve problems more quickly, especially for calculus. Additionally, if you get the TI-89 Titanium (extra memory), you can get a lot of great programs for calculus from TI's program archives. When I was preparing for the AP Calc BC exam, I was about 80% on non-calculator problems, but I hardly ever missed calculator questions (and I did them faster, too). Also, don't worry about your calc class--if you know the TI-89 well, it won't matter if the TI-83 functions and syntax are different. Trust me, three of my friends and I had TI-89's all year, while everybody else was using 83's, and we never had any problems.
