this problem is in the improper integrals section but i just need help taking the integral. the bounds are from 0 to positive infinity.(adsbygoogle = window.adsbygoogle || []).push({});

xarctanx/(1+x^2)^2

i tried doing a trig sub x = tan θ, which gives θtanθ/(secθ)^2 I believe, which gives θsinθ/(cosθ)^3. I couldn't find anything to help me from here, so anything is appreciated. Perhaps I did one of the earlier steps wrong. Thanks in advance.
