Ti-89

<p>I have been using my TI-83 Plus for five years now and it got me through a few chemistry classes and physics classes, as well as, calc 1-3 and differential equations. My question is how do chemistry, physics (4 series and upper division), and math (20e, 20f, and upper division) professors feel about the TI-89 (since i'm thinking about getting one as it will be useful, but i dont know if i will be able to use it on hw and tests)?</p>

<p>chemistry- only scientific calculators allowed.</p>

<p>math- no calculators allowed on exams. you can use it to do your hw though, it's faster.</p>

<p>A TI-83 is sufficient.</p>

<p>I've never seen a professor make a distinction between a TI-83 and TI-89.</p>

<p>Some math classes do allow calculators.</p>

<p>hmm, thats weird cause every single math class that i have been in except one has prohibited TI-89's because they can do symbolic differentiation and integration and such. If calculators are allowed, are TI-89's allowed? Also, what about physics classes?</p>

<p>Graphing Calcs are allowed in physics classes. But you don't need them.</p>

<p>None of my math classes allowed any calcs...</p>

<p>How many math classes have you guys taken?</p>

<p>My 20E class allowed a calculator.</p>

<p>why switch in the first place? TI-89s seem so much more confusing to me than TI-83s...though i guess it can do some pretty cool stuff.<br>
and i've taken 2 math classes that allowed calulcators...</p>

<p>the reason to switch stems from both learning more about the TI-89 (and getting to the classes where it will help) and accidentally dropping my 83 out of an open pocket in my backpack and partly cracking the screen. Its still usable, but the crack can get in the way sometimes. </p>

<p>Yay, ill be taking 20e in the fall, so thx for the info slorg</p>

<p>I believe most 20E classes forbid calculators.</p>

<p>that sucks, who did you take for 20e that allowed calcs</p>
