I've done the first part of the question but I'm not sure about the second part. I have some special results that might be required for it but they possibly aren't required.

for the second part, use induction to prove that
do you know how is it done ?
This is not the required proof. I have a book that has a similar proof to that required starting from an identity for r^2. This thread was on the second page and would not get any replies now if I weren't putting it back up to the top.
