I think this solution is beyond my level of knowledge. How did you get (n-1)(n+1) out of the sum? I sadly don't know about uniform convergence. Is there any way to do this with simpler algebraic methods?
Im not sure if it is related to calculus but,
Calculate the sum
\sum^{\infty}_{n=0}\frac{(n-1)(n+1)}{n!}
exactly.
I tried to to partial fraction decomposition but couldn't find anything.
