Is there a calculus program for the computer that anybody knows of that can do calculus? I already have a TI-86 calculator, but it won't work out an expression like a TI-89. Im thinking about buying a TI-89, but I'd rather not if I could find something that would work on the computer.

MATLAB. No, it's not free. I've had a TI-89+ for a few years now. Keep in mind when I say this next thing, that I used to write videogames for my TI-83: the TI-89 is so complex I've barely ever used its full power. I'd get the TI-89+; it's the last calculator you'll ever need.

i had spacetime 3.0 and pocket calculus that i used on my cellphone with windows mobile, so if you have a windows mobile phone you can get those. they worked great. got me through calculus 1 & 2

Thanks fellas. I'll try Pocket calculus and spacetime first since I do have a windows mobile phone. Plus, they have trial period... Me love the internet. Sounds like the TI-89 is the way to go though. I have an 83+ and TI86 that would just rot though if I bought that.

ya, the ti-89 is good stuff. if you're just going to be doing it on your computer you can download an emulator and the ti-89 rom straight from texas instruments website. although legally you're suppose to own a ti-89 if you download it. although if you need to use a calculator for tests just buy the ti-89. my calc teachers didn't allow calculators on tests though so it didn't really matter for me

My profs didn't allow calculators on tests either. I used mine anyway, and I used it to solve pieces of the problem at a time instead of all in one shot, so I could show the steps. That's all they cared about, and I got good grades -- except in Differential Equations, which was confusing as hell, and Statistics, which made me narcoleptic.

Sorry guy, but no one will be riding my ass It was a link to a torrent of matlab. My bad for posting it since it was obviously against the rules.

Thanks. I was dumb at first. I was looking for the emulator on TI's website. I installed it, but it isn't that easy to read. also, when I open it I can't figure out how to get it on the screen. It opens and flies to the top of the screen. The only way I can resize it is to send it to the other monitor via ultra mon, and resize it there. *sigh* such a noob

I have no idea why you people are suggesting Matlab for this guy. He would be better served by a good symbolic mathematics program like Maple or Mathematica. I mean, sure, he can install the Symbolic Math Toolbox in Matlab, but that's just an addon that uses the Maple engine anyway. Do you people even use the programs you're recommending, or are you just recommending Matlab because it sounds sort of like "math?" edit: Just so you know, the "Mat" in Matlab stands for "Matrix," not "Math." And it's great for solving transfer functions, solving 1000 simultaneous equations, etc. Notsomuch with the solving of a simple integral.

MAPLE! That's the name of the program my physics prof used. The only one I could remember was MATLAB. I much preferred Maple.

Maple is indeed badass and very, very simple to use. Matlab is badass as well, but not easily picked up.

I looked up matlab, and it's not what I needed. Thanks Bovine. I will have to check out Maple. Do you own a TI-89, Bovine? I just dont know if it's worth it for me to spend the money on one. I have a TI-86 and a TI-83 already(never use the 83, got handed down to me). Maybe I should sell the TI-83 and just get the 89. We can't use the calculator on the test anyways, that's why I dunno if I want to spend the money. After this semester my TI-86 will be good enough I bet.

I own a TI 89 and an HP 50g. Get the 50g. It's by far the superior calculator, and it costs ~$20 less than the 89. It's what professional engineers use (if they aren't using Maple or Matlab). I've never seen the 89 out in the workplace. edit: You should also check your campus computer store. I know that at UT, we can get Mathematica (which blows any graphing calculator out of the fucking water) for $30.
