I have to integrate the function : ln(x)/(1+x²) between 0 and +inf.
I can't find the solution.
When I try an integration by part, I feel like running around in circles...
On the exercice statement, there is a suggestion: set x=(1/t) ...this don't help me...
The solution I have to find is 0.
Could you help me to resolve this?
Thanks in advance!
