<p>Is it really worth buying for the Calc BC test? Do a lot of universities recommend this calculator? Also, is there any chance that Texas Instruments might release an updated version of TI-89 soon? I'm reluctant about getting a $150 calculator, and my school doesn't have it for borrowing.</p>
<p>if u dont know how to use it, then its prolly not worth the money. use an 84 or 83+</p>
<p>well, this is just my opinion, but I loooooooovvve my 89. Pretty much everyone in my BC class has one and whenever they forget theirs and have to use a classroom 84, they all complain because there's so much it can't do. so I think it's worth it, but i guess you should do some research and figure out which features you really think you need.
(then again, if you've been in the class all year and are used to doing everything you need with that, then you're probably fine)</p>
<p>and i agree with omnivoroushippo. if you don't know how to use it, then its completely worthless.</p>
<p>I have a Ti-89 too and I really like it. It's just a lot spiffier than the other Ti's and even though I definitely don't know how to make full use of its capabilities, it'll definitely come in handy on the AP exam.</p>
<p>You definitely have an advantage on the test if you use an 89 so you might as well. If you look back at last years free responses, there's some definite integrals that you simply don't have the time to do by hand.</p>
<p>The TI-89 gave me the confidence I needed perform. Had I not gotten it, I would not have the confidence I needed to succeed on the AP tests. </p>
<p>Seriously, it will give you lots of advatages. You can program your own algorithms for doing volumes for instance !</p>
<p>my school issues the 89 to all cal students and i love it! it def makes solving integrals much faster, which comes in handy on the exam. it also has a much better interface [IMO] than the other calculators.</p>
<p>Absolutely not. Ti-84s can solve derivatives, integrals, and single-variable equations too. Simple programs (for anything below calculus) can be just as easily made on the 84. </p>
<p>nInt, nDeriv, and Numeric Solver, respectively.</p>
<p>Seriously. There are people with 89s who didn't even know what half of the things on their 84 did. Besides, most university-level math courses won't allow you to use a graphing calculator (most allow only scientific calculators).</p>
<p>Meh, there's no way it is as streamlined as the 89. My school checks out 89s to all the calculus students though, so I dunno if I could justify the cost.</p>
