NeoDevin: Thanks, that's a helpful response. The "." and "->" operators are new to me. I could not find anything about them in the documentation. They appear to designate a substitution. Also, I'm confused about your use of (A+B) & (A-B) rather than (M+L)/2 and (M-L)/2. I really don't...

A Specific Problem (following Einstein) These two equations follow a derivation of the Lorentz transformation by Einstein: (but here we are just interested in the math) x+ct = M(y+cr) x-ct = L(y-cr) x & t are spacetime coordinates in one reference frame; y & r are the corresponding...

I want to get some math software, something that does everything. :) (or as close to that as practical) Of course I want it to be really easy to use. :) Yes, I realize that all of the above is impossible. I guess the best question is, which is most popular among, say, physics grad...
