Hi Tyler,
The unix world has a number of command line utilities like bc, mathomatic,
octave or singular, as well as libraries like lapack, GLPK and GMP. If you
Google for terms like physics formulae you will find sites like:

Subject: accesible math resources
Hello all,
I wanted to get in to some design with physics, building simulations, etc. I
had some ideas for some fun games, though I have a problem.
I want to learn about vectors, trig, calc, etc. Are there any accessible
math resources you guys used? I do great if I can sit down and teach myself,
or if I can understand the problem, it's just getting everything that's the
issue.
Second, would someone happen to have a list of formulas for physics
calculations? I'd like to play around with some of those.
I'd also like to find a decent calculator (preferably software) that will do
what I set it to, using variables and etc.
I heard about matlab, but I believe that costs. I just want to play around
with it, so investing cash isn't an option at this point. It might, if I had
the cash to invest, but that just opens up a whole new set of
doors(problems)
Last, I'd like to learn how algos work such as compression and encryption.
All the info on these I've found are decent, but they tend to show their
formulas in graphics, which is no help at all.
Thanks,
Tyler Littlefield

My programs don't have bugs, they're called randomly added features.
