I'm stuck with this definite integral : [tex]\int_0^1\frac{ln(1+x)}{1+x^{2}} dx[/tex]

2. Relevant equations

The various "standard integrals".

3. The attempt at a solution

I just don't know where to start, or how to do it. I tried various substitutions but none of them worked; I also tired doing it by parts but that didn't work either.
