<p>Well, I'm preparing for Calculus BC. Now I'm looking for a good graphing calculator. There are so many types of TI, such as 83,84,86,89. It's hard for me to choose a right one. Peterson's recommends to use 83, but I don't want to buy another for college study. My major will be engineering, so which one should I choose?</p>
<p>I'll really appreciate your reply.</p>
<p>89 for engineering. I don't see why the 83 is recommended over the 89 since the 89 has some useful functions for the FRQs and pretty print helps you in typing tricky equations with a lot of parenthesis. Some professors prohibit the 89 on exams however but it is allowed on the AP Calc exam.</p>
<p>89 is the most useful for calc BC BUT it's also the most confusing. I wouldn't use it unless you're CONFIDENT you know how to use it.</p>
<p>i agree its the most complex, but once you learn how to use it, it can do almost anything. It is so powerful and will make calculator sections on the AP test so much easier.</p>
<p>What about HP 50g??? yeah, less practical for calc bc, (b/c not many programs written for it) but fast processing and key strokes and RPN so I think that one is better in the long run.</p>
<p>The TI 89 is not recommended during classes because most teachers are only familiar with the 83/84...the 89 is set up differently, so a lot of the functions are accessed in completely different ways. You probably want an 89 if you are going to end up in engineering, but you should be prepared to learn how to use it on your own. I've never even heard of the 86...</p>
<p>TI 83 silver plus/84. The 89 is banned in most high school exams and
quite a few engineering school math and physics exams.</p>
<p>:)</p>
<p>Yeah, that's a good point, a lot of teachers don't allow the TI89.</p>
<p>A lot of the math teachers I talked to recommended the TI 84 plus silver edition. It has a lot of programs and memory space, plus seems to be easier to use than the TI 89. Of course, some of my friends who have 89s like them a lot better than the 83/84. And I agree with a lot of people above--the 89 is not allowed for some tests (SAT I think) plus they usually aren't compatable with the calculators that teachers are supplied with, therefore your teacher probably won't be able to help you much with your calc because they may not know how to use it (aka my calculus teacher). Anyway... I vote for the TI 84 plus silver edition (and it's wayyyy cheaper now than it was three years ago)</p>
<p>in my school ti89 is the standard calculator and all students are required to purchase one. and so far, we've loved it. so go figure.</p>
<p>ti89 is allowed on sat, calc teachers dont let us use them during tests because it just destroys calc AB, especially indefinite integrals</p>
<p>Yeah, doesn't it have an infinity button?</p>
<p>ehhh sorry. I guess I was wrong about the SAT not letting you have a TI 89. Just a word of caution: don't get too dependent on your calculator. You need to remember that you don't get to use it for half the test</p>
<p>In our calc class, they can use the 89 even, but it usually is a problem where there 89 isn't any more helpful than the 83. For instance, the integrals tests were all non-calculator, with the exception of area/volume tests where fnInt was allowed on the 83/84.</p>
<p>84 Plus .</p>
<p>89 hands down</p>
<p>Well, it seems hard for me to choose a right calculator.
84 silver plus or 89? That's a question.
89 is banned in some exams? Then I have to choose a calculator according to specific policies of classes and colleges?
I don't use calculators often. I want to purchase one just for the calculator problems on standard exams.
Thanks for your advice.</p>
<p>84 plus, silver edition if you can. The 89, though it does a lot of work for you, is banned on many competitions and tests. It would be more of a hassle if you kept having to switch calculators. I have and 84 plus silver, and it really works well.</p>
<p>I have had a ti-89 titanium for about the last 4 years and i have competed in numerous math/calculus competition and none have banned a ti-89. Also my sister went through college (electrical engineering) with only a ti-89. I don't think its banned. Its the most useful and powerful. The 89 is the obvious choice, and buying anything else will just waste money when you are forced to buy a ti-89.</p>
<p>I have the TI-89. The manual is useless. It takes quite a while to be able to correctly use the calculator. </p>
<p>Also, the new TI N-Spire came out. It is allowed on SAT and Ap tests. Anyone try it yet?</p>
