Use the integral test to determine if this series converges or diverges: sum from n=1 to infinity of n/(1+(n^2))
Integral test: a series and it's improper integral both either converge or both diverge
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.
