I still don't see how that proves it seems like a restatement of the hypothesis.

I'm trying to show that the quotient of two power series Sum(n=o, infinity)[an*z^n] and Sum(n=0, infinity)[bn*z^n] is the power series Sum(n=0, infinity)[cn*z^n] where c0=a0/b0 and b0cn= (an-Sum(k=0, infinity)[bk*c(n-k)]). Is there a way of showing this by (Sum[bn*z^n])(Sum[cn*z^n])=Sum[an*z^n]...

thanks i see it now

how can I write f(z)= 1/(c(1+z)) as a geometric series with radius of convergence 1, where c is a complex number?
