Hey quick question

Anyone know of an open source program like Mathematica? I know this probably isn't likely at all given how difficult it is to make such a project, but I need to evaluate a ridiculous formula with three different parameters and it just gets jumbled in my ti-83 and I've given up trying.

Thanks in advance for the consideration.

Try Maxima perhaps? Open source, quite capable, might be a bit confusing at the beginning though.

If it's graphing software you need, try Graph: http://www.padowan.dk/graph/

I've also heard people suggest Maxima for this type of purpose.

Personally I'd do it in Matlab :3

edit: how can your ti-83 evaluate anything difficult? I'd think you'd need an 89 for that...

Try the new wolfram alpha? :o

Just refresh until it does it. Lots of people using it.

scilab, sage, octave
I haven't tried any of them, but they're the most prominent open source mathematica/matlab software out there

I use Sage. It takes a bit of getting used to, but it works pretty well once you get the hang of it.

its a bitch, and an utter failure.

if you register for a free account, you can use sage online here:

That's probably the easiest way to use it if you're only going to do one or two calc's.
Otherwise, life is pretty hard really. I think they want you to install a VM, and then access it through firefox. Install instructions (if you haven't found them yet) are here:
