1. The problem statement, all variables and given/known data Use the integral test to determine if this series converges or diverges: sum from n=1 to infinity of n/(1+(n^2)) 2. Relevant equations Integral test: a series and it's improper integral both either converge or both diverge 3. The attempt at a solution see attached - I need help finding the integral. I tried using an online integral calculator, symbolab but it says there is no integral. I'm guessing there is some way to split this up into pieces that I'm not seeing. Please help.
