The equation is: Summation n=1 to inf x^n/(n+1)
When the endpoints are checked at x=1 - 1^n/(n+1) is rewritten as 1/n - 1. Can somebody show me the validity of this?
Hi p75213...are you a Stargate fan? (if you get that, you are )
Anyway, your problem is in the form of the ratio test for convergence, which basically lets you compare your series to a geometric series to determine it's behavior. I think you'll find your proof here.
Hope that helps,
