<p>I'm going to be finishing up mv calc/diff eq this year, and next year I will be taking linear algebra (If I can find a class near me :)). However, I've heard that 89s are not allowed in higher math classes (T/F?)? </p>
<p>So would a TI-89 be a smart investment? There seems to be a pretty big learning curve, and I don't want to get screwed over on the SATs or something (I would be no longer familiar with the 83/wouldn't know how to use the 89). </p>
<p>Also, if I do get one, should I get an 89 or titanium?</p>
<p>You might as well get titanium if you're going to get one, it's more upgraded and doesn't cost too much extra, you get more memory, more applications</p>
<p>If you were going to do calc, i'd say get the 89 because it makes things much less time consuming .. but I've never really heard from someone taking that high of a level math class so I really don't know if it would benefit you. But I'll tell you this. I have an 89 and I have a feeling I'll be using it for the rest of my life, even when i'm 30+ and have to calculate taxes, balance the bills, etc</p>
<p>im taking multivariable calc this year and i never use my 89 (we use maple). however, it is extremely helpful in physics, chem, sat IIs, it was helpful in calc. honestly, i would recommend the upgrade to the 89 as it is so useful in so many ways, that just because you can't use it in one math course is no reason to discredit it.</p>
<p>i've been using a ti-89 for 5 years. even though it isn't the new titanium edition, its still tremendously more powerful than any other. it has a built in "solve," and "derive" functions to name a few. the interface, in my opinion, is also a lot more user-friendly</p>
<p>I have an 86, and enjoy it because it's about the most powerfull thing you can use on a lot of tests, but I would have a hard time not buying an 89 now. It's a really nice calculator...definetly worth the money.</p>
<p>I have the 89 titanium which I just ADORE because it does pretty much anything you'll ever need for you (pre-programmed!). However, I know that we're not allowed to use it on the AP tests, which is why I'm not allowed to use it for AP Calc, and that you can't use it on the ACTs either.</p>
<p>Yeah, I'm finishing up multivariable this year, and I got through BC with an 83. However, I've heard 89s (even 83s...) are prohibited from higher math classes. Is there any truth to this?</p>
<p>I love mine - its all I have used since algebra 2. Screw the ACT's, just take SAT if that is your concern. BTW you CAN use the 89 on the AP exam. Also it was created for higher level math classes - so it should not be banned, expecially in some engineering classes which REQUIRE them. Of course you might have your odd HS teacher that bans them but other then that you'll be fine. Who have you been talking to? IMO the screen is reason enough to get the 89 - it is that much sharper. Ti - 83 screens aren't even fit for dogs imo. TI86 is a little better.</p>
<p>You should get one, especially for multivariable calc. I have never used my 89 in linear algebra sicne much of it is proof based and the euqations we do are pretty simple, or we create a program in MATLAB to run it (i.e. power method for finding eigenvalues and stuff). But you shouldn't rely on a calculator as a crutch because most high level math classes don't allow calculators as you might have guessed, it's mostly jsut used for homework to check the correct answers.</p>
<p>Last I checked, it was around $150 during a sale time right before school. And yeah, it's pretty nifty for integrating and deriving functions and the like.</p>
<p>My Ti89 has a problem: i'm in a statistic class and i wanna get in F5 "Distr" but instead of "Distr" i have 'pgmIO' .
Does anyone know how can i get in F5 "Distr" instead of "pgmIO?"</p>
<p>Or i just nedd to get "poissoncdf", "poissonpdf", "binomcdf", "binompdf"!!</p>
