Improper integrals step by step solutions

Posted 11 years ago

Hello, I'm trying to get step by step solutions for some improper integrals such as: integral of log(x)/(1+x^2)^2 from 0 to infinity. But i dont get this option, i only get the solution. I'm new to wolfram alpha pro.

are you miss spelled something ? cuz integral xlogx /(1+x^2)^2 is quite easy for solve... but log(x) ??? not so easy. only log(x) you get...well...

Yes im sure it is correct, I really don't have an idea on how to solve it, if you introduce the integral limits from 0 to infinity it gives this result: -pi/4 but there's no step by step solution option.
