# Math Help - INDUCTION PROBLEM

1. ## INDUCTION PROBLEM

I have a question.This one's either really hard or really stupid

it's an induction problem.
$(1 - 1/2^2) * (1- 1/3^2) * ....... * ( 1 - 1/n^2) = (n+1)/2n$

been solving it since past several hours. but i am not getting my L.H.S = RH.S for this one.
I started with proving if p(n) then p(n+10

so L.H.S = [1 - 1/(n+1)^2] + (n+1)/2n

R.H.s = (n+2)/2(n+1).

I can't just prove them equal.

Note that $\frac{(n+1)}{2n}\cdot \left(1-\frac{1}{(n+1)^{2}}\right)=\frac{n+2}{2(n+1)}$
