?!?!?!  Did I read that correctly?  Days?  Um, this is a homework problem
for a class I'm taking, and it's due Wednesday :-)

A numeric solution is prefectly acceptable.  I just thought that there
would be a fairly simple symbolic solution...

Seriously, is that sort of run time something I should expect?  I suppose
I've been spoiled by the expectation of more-or-less instantaneous answers
from interactive programs, so when Maxima (or anything) just sits there, I
figure either I've done something wrong, or the program's broken.

I guess my next bunch of questions will be things like how can I tell if
Maxima is actually working on something vs spinning its wheels.  Is there
a way to have it tell me something like "Hey, this is way complicated.  
If you want an answer, come back in a week or so..."?

Thanks,
