<p>Is it worth it to buy the 89? i am a junior and i will be using it for AP calc AB , Stat, SATs and off course APs next year etc. Is it worth the investment to buy the 89?</p>
<p>I’m in love with my 84. I used it for AP Stats, and I’m using it for Calc AB right now. It has a terrific stats package (all the tests, lists for statistics, etc). If you get the 2.53 OS it becomes godlike for calculus too. You can do the integrals/derivatives straight on the homescreen instead of fnInt and the like.</p>
<p>Of course, the 89 will calculate indefinite integrals and derivatives, but it’s much more complex than the 84, and its statistics package is less robust. I think that since you’re going to be taking Stats as well as calc, you should get the 84.</p>
<p>For stats on the 89, all it is is a series of button pushes. I learned to use them quickly. </p>
<p>I suggest you get an 89, and work with it from the start.</p>
<p>Already have the 84.i was merely weighting as to whether i should purchase the 89 for Math II and Calc AB this year.</p>
<p>I really thought this was going to be a comparison of getting an 89 (b+) versus an 84 for a grade. Wow. 84 is useful and accepted. 89 is more complex but more powerful, but not as accepted for use in tests etc.</p>

<p>^NSpire is really, really confusing. </p>
<p>The 89 is much more powerful, and because of its power, it’s often not allowed by teachers in their classes and by some standardized tests (ACT bans it). Learn to use both the 84 and 89. You can use both at the same time on the Math II and AP Calc tests (and SAT and any other calculator-permitted AP test).</p>
<p>89 is so damn confusing. Arghh…</p>
<p>89 is so freaking simple to use.</p>
<p>lolzzzz i think i may get it. will be useful in college i’d assume.</p>
<p>I’d ask your math teacher.</p>
<p>At my school you’re screwed if you have an 89, at least for Stats. Our books is from 2001 and our teacher basically only knows how to use 83’s and 84’s… because that’s what the book recommends. My high school recommended TI-83’s when I was in the 8th grade, because that’s the set standard for my high school.</p>
<p>I have an 83 and I love it to death. I can do everything on it in Stats.</p>
<p>yeah i def wanna use it for my AP stats but it could be very useful for CALC</p>
<p>Wait for the TI-Nspire CX to come out. It has already been announced. It will have 3D graphing capabilities along with a color display. Yum</p>

<p>I thought you were ■■■■■■■■ (no offense) but then I looked it up: [TI-Nspire™</a>; CX CAS Handheld by Texas Instruments - US and Canada](<a href=“TI Products | Calculators and Technology | Texas Instruments”>TI Products | Calculators and Technology | Texas Instruments)</p>
<p>My reaction: Holy s–t. </p>
<p>(Note: The TI-89 already has 3-D graphing features, but definitely not color).</p>
<p>lol when i first saw this i thought you were referring to school grades and was confused for like 20 seconds when i read the first post.</p>
<p>89 = ez moad :D</p>
<p>The 89 is amazing IF you know how to use it. It’s not that hard to learn, though, and it’s really helpful in lower level math classes.</p>
