b) show further that
really need help with this one, its bugging me so much that i cant get it
So for the factorial thing, you can do it by induction.
If n=0, then but . So it is ok.
(by the recursive formula)
It's easy to prove that this equals , which is what you are looking for.
Question 2. > similarly, find a recursive formula for
