This wouldn't be a homework problems would it?  I think it really
defeats the purpose of setting such problems if you don't at least try
to do them yourself. In fact, I'll be somewhat disappointed if readers
of this group just dive in and answer your question.

BTW, it is quite likely that your Professor or TA reads this group :-)
