I'm sorry, according to the rules of PF, HW helpers are not allowed to outline complete solutions for users.

If you would care to make an attempt at solving this problem, however, we will gladly provide comments and help for the portions where you get stuck.

It's like taking a test: if you don't know the answers to any of the questions, at least write your name at the top of the paper.
