What calculator should I buy for this year?

edited August 2009 in AP Tests Preparation
I'm going to be a Senior in High School and am taking AP Calculus BC and AP Biology. I was wondering what calculator you guys recommend for this year, and possibly to continue on to college?

I have used the TI-84 Plus Silver for the past 3 years but it broke this year accidentally when I dropped it while taking the ACT test :( So I've been looking mainly to either get the same calculator again or purchase the TI-89 Titanium for around $20 more.

Would the TI-89 Titanium be worth it? Would it help more in tests/college/SAT Lev II's than the TI-84?

Thanks!

    TI-89 is extremely good for calculus and it would help you in a lot of mathematical sciences and math classes. But you should know that in college, some math professors, including those who teaches calculus, only permit the use of scientific calculators.

    I do NOT recommend a TI-89 because they are restricted on many exams.

    ^It's allowed on AP and SAT tests. And professors who don't allow the 89 are usually the ones that don't allow anything beyond a scientific calculator (if you're lucky...).

    I would honestly recommend that you buy whatever calculator your teacher will use for demonstrations in class.

    If the teacher won't really demonstrate much in class, then I'd stick with the TI-84 that you're used to, personally. The benefits of a TI-89 on the exam are virtually nil.

    What's the difference between a TI 84 Plus and a TI 84 Plus Silver?

    @cyberchondriac: more memory, more apps, etc.

    @OP: I definitely would suggest TI-89 Titanium - it's a really good calculator that is designed for AP Calculus and beyond. The thing I like about it is its implementation of actual variables. With you experience with the TI-84, you would have noticed that every variable has a value of 0, unless u assign to it a number. Well, on the TI-89, they don't hold 0, they're ACTUAL variables. For example, if you type x+x, then your answer will actually be 2x. This kind of stuff comes in handy sometimes. Plus, it possesses the ability to calculate indefinite integrals, and derivatives in general, as opposed to the TI-84 which only calculates definite integrals and derivatives AT A POINT. So, I would definitely go with the TI-89.

    Cyber, the Ti-84 silver edition has like a periodic table installed and some other applications.

    The TI-89 is slow as hell. I would recommend the TI N-Spire CAS. It has all of the functionality of the 89 plus way more, and it is FAST. It's also allowed on the APs and SATs.

    I'd say Casio 9850GC Plus.There is a special menu and it has colors (very useful for graphs). Although ive never really used a TI, i dont think it has a menu and you really need to learn it.

    It is really up to you.
