The Kronecker delta_m,n function has several series definitions, one is
integral_0^2 sin(m pi x / 2) sin(n pi x / 2) dx. If we replace n=0 then this appears to sum to zero, but that makes no sense. The result should be a function that is one when m=0 and is zero otherwise. I cannot reconcile this contradiction, please help!
