The ’moments’ <t**n> of the distribution p(t) are defined as: <t**n> = integral from (0, infinity) p(t).t**n dt (1) where ** denotes to the power of Show (analytically) that <t**n> = n!τ**n (2) Hint: Use integration by parts to show that <t**n> = nτ<t**n-1> (3) and use mathematical induction I have solved the integral to get equation 3 but i can't begin to think on where to start the mathematical induction. Its been so long since i have done it. At first i thought that doing <tn>.<tn-1> = blabla would work but i get the answer blabla = nτ<t**n-1> . (n-1)τ<t**n-2> but i really think im missing the mark by alot. Sorry about the bad formatting.
