Ah, that sort of makes sense. Thanks!

This brings up a question: how do I know which functions to call to simplify something? If you look at some of the examples that come with MuPAD (specifically the Webster tests) you'll see stuff like combine(expand(normal(combine(....)))); how is a user supposed to know which to call?
It gets even worse with trig functions...I entered that huge trig mess from the guy's Maple post this week to see how MuPAD would do, and it simplified it a bit, but couldn't get as far as the other person's post for Mathematica 3.0's FullSimplify.
