Sorry, I intended to write u = 1 + arctan(v), not u = arctan(v). The 1 goes to zero either way though, so I still have the same problem of getting ln(0).
Homework Statement
Evaluate the integral: ∫(0 to ∞) [dv/((1+v^2)(1+tan^-1(v))]

As you can see in the image, I try u-substitution and then take the integral. I end...
