TI-nspire vs. TI-nspire CAS vs. Ti-89 Titanium

Pre-College Issues High School Life

<p>I'm shopping for a new calculator. I currently have a Ti-84, but I'm giving it away to my younger sister and I'm looking for a more advanced calculator.</p>

<p>Which one would you recommend?</p>

<p>I'll be a senior and I'll be taking IB Calc HL and AP Calc BC. I want a calculator that would be useful for college. I'll probably be taking multi-variable calc and linear algebra.</p>

<p>So which one do you recommend:</p>

<p>TI-nspire
Ti-nspire CAS
TI-89 Titanium</p>

<p>I heard that the last two have "CAS" functionality. Can someone explain what that is?</p>

<p>Thanks.</p>

<p>I heard the TI-89 Titanium is good for calculus (if you figure out how to use it). </p>

<p>We all use TI-84 / TI-83 on the AP Calculus exam and I've never seen anyone at my school use the 89, mostly because our teachers don't know how to use the 89s either. 89s are highly recommended around here though...</p>

<p>Also, if you get a calculator that is too "smart", professors in college might not allow you to use them, so think about that before you decide to buy one. I've heard from college friends that they are not allowed to use the TI-89 on college calculus exams.</p>

<p>I hope you know IB doesn't allow TI-89. The highest they accept is TI-84 plus. At least that's what my math teacher said.</p>

<p>nSpire CAS ftw</p>

5

<p>Is the TI-84 and 82 acceptable for the ACT and SAT?</p>

6

<p>TI-84 and lower are fine for anything.</p>

7

<p>I know for a fact Ti-89 is banned.</p>

8

<p>^ Yeah, I know that, psssssssssh.</p>

9

<p>TI-89 is fine for the SAT and the SAT Subject Tests, but it's not allowed on ACT.</p>

10

<p>The 89 is great, however you wont be able to use it in college ....well at least the first 3 semesters of calculus, I dont know about any other more advanced math courses</p>

11

<p>i loves me ti-83+. i've kept it in very good condition</p>

12

<p>I have an 84, and I really like it. I've had it since 8th grade, so I don't think I'd adjust very quickly to a new calculator anyway. If you look around for sales, you can find them for $90 or less. Some stores will try to get $130 out of you for the TI-84, but they're just ripping you off.</p>

13

<p>you can get a ti-89 for 90 of ebay as well. But out of the 3 the 89 is the best.</p>

14

<p>TI-89 Titanium--best one out there and will last you well through college.</p>

<p>Helped me get 5 and 5 on AP Calc AB and BC</p>

15

<p>Ti-89 FTW
btw to those people in college who coudnt use a Ti-89 in their math classes, what did u use instead??</p>

16

<p>^ I use TI-84 Silver Edition. Our class is split between TI-83s and TI-84s.</p>

17

<p>I just saw the n-spire for the first time yesterday in French class. It looked a little strange, but basically it seemed like a Ti-84 w/ more computer/application accessibility/template like 89 titanium. It also costs less than Titanium. I would still stick with titanium.</p>

18

<p>I have all three and the TI-89 is by far the best!</p>

19

<p>why would you need all three?????</p>

20

<p>I don't, the only calculator I have ever bought was the 89 back in 7th grade, the others I've received as prizes in math competitions (ARML, MATHCOUNTS, etc)</p>
