</p>
<p>Yes, that’s exactly my point. Thank you.</p>
<p>
</p>
<p>Because if I’m going to spend a large chunk of change on a calculator, I want to be able to use it as much as possible. There are a lot of places where the TI 86, 89, and 92 are banned.</p>
<p>tetra, my brother goes to an engineering school and his professors never let them use 89s. They want to see you can do it, not that your calculator can.</p>
<p>I have only ever had a TI 84+ and it got me an A in calc and a 4 on the test. </p>
<p>You don’t need an 89. They are a pain and not worth it. People become dependent on them and then can’t do integrals and derivatives by hand when they get non-graphing calculator quizzes and tests. We weren’t allowed to use them at all on tests and quizzes at my school.</p>
<p>Plus, you definitely don’t need one for the ACT or SATs. I am not extremely good with math and still managed to get an 800 on Math 2 of the SATs and a 35 on math on the ACT without a calculator at all (I have a bad habit of forgetting to replace batteries), so it’s not at all necessary for an 89 for those. There’s nothing calc related on them.</p>
<p>Roman, I don’t know about you, but I would consider your math skills very impressive if you can get an 800 in Math II without a calculator! You can’t bring an 89 to the ACT anyways, but 35 is impressive (and get a solar scientific calculator if you have trouble with batteries) </p>
<p>Personally I don’t overuse the calculator. It does help, but that aside, you should know how to do it by hand. If I look at a very long integral and see a calculator allowed on the question, than I am obviously going to use the calculator to solve it and not lose time, since that question was obviously meant for it. But, you need a balance of both manual and calculator work. </p>
<p>Anyways - you definitely need a graphing calculator for some of the volumes that you will be integrating. Which is why i suggest buying an 89, since it probably isn’t much more expensive than an 84 silver (which i know someone who got it and regretted it in favor of the 89). Maybe understanding how to use it is hard. In the end, just buy a damn graphing calculator…</p>
<p>But i am also very curious - does anyone own a TI-Inspire? I have heard that the graphing is WAY faster than the Titanium, which I have always been annoyed at the 89 for letting me down when I want to visualize the equation.</p>
<p>
Yea. I’m debating whether to get an 89 or an TI-Inspire :[ Any opinions? </p>
<p>I think I’ll just borrow my friend’s 84 for the ACT.</p>
<p>
</p>
<p>That’s basically the main point of the nspire. It has a much better screen, more RAM, and probably a better processor.</p>
<p><em>sigh</em> if i knew that then I would have worked harder with my team to win competition and get us free TI inspires. Oh well, it would really only help in tests and save me a few seconds really.</p>
<p>I don’t know about the other applications about the TI inspire, which is why im curious because it is supposed to be the new TI 89 Titanium.</p>
<p>The nspire isn’t an updated 89. It generally has less features but better hardware.</p>

TI89
…Trust me, its in all the medical books</p>
<p>
</p>
<p>That depends on what kind of math you’re doing. For statistics, everything precalc, and early levels of calc, it’s superior*. I think it also has a better graphical interface. </p>
<ul>
<li>Of course, even the 83 Plus is superior to the 89 in statistics. Much better button layout.</li>
</ul>
<p>A TI-89 is totally unnecessary for AP calculus. I used my TI-82 (that I bought used on ebay 5 years ago) for the entire class but borrowed an old TI-83 Silver for the BC exam.</p>
<p>In the calculator part of the AP exam I think I used the calculus function only a couple of times. Most of the calculator portion can still be solved by hand. The only calculus help the calculator can really provide is to save a good amount of time on the couple of long definite integrals in the exam. But those can be solved even on an TI-82.</p>

<p>Well, if u enjoy calculator programming (my favorite pastime) get urself an 89!
I made a “Calculator Hero” program (think guitar hero but instead holding a calculator sideways instead of a plastic guitar) but it just doesn’t run that smoothly on an 84! Btw, if any1 wants the code to Calc hero just ask lol! Ill post it right here</p>
<p>^haha nice! i’d ask for the code but i can’t even figure out how to run standard programs…and besides i have no idea where my ti-89 is anymore, sadly</p>
<p>^thx, u don’t need an 89 to run it, i made it for 84. It’d be quicker on an 89 tho</p>
<p>i shoulda figured out how to program my calculator. (or at least run games.) it would have saved me many hours of boredom in ap stats</p>
<p>My dad got me a TI-Inspire. It’s got lovely graphics.</p>
<p>It came with the 84+ silver pad too, so I can just switch it if I need to anyways.</p>
<p>@ fizix</p>
<p>Ya I got into calc programming due to boredom in math class (although I ended up programming in german and english class too, not good lol)</p>
<p>it’s ironic because [url=<a href=“http://xkcd.com/519/]http://xkcd.com/519/[/url”>xkcd: 11th Grade]http://xkcd.com/519/[/url</a>]</p>
<p>I wrote a few programs, but never games. Mostly AP scoring guides, though a few long chemistry programs.</p>
