1. The problem statement, all variables and given/known data Find the sum of the infinite series, if the series converges. infinity E n = 1 (2) / (n^2 + 2n) 2. Relevant equations .. 3. The attempt at a solution I believe this problem doesn't look very hard, I think all i really need to do is divide the denominator and numerator by the largest n in the denominator. so it would look like this --> (2/n^2) / (1 + 2/n) which would become 0/1 so converges to 0? but what is finding the sum of the infinite series? help here please. Thankyou.
