# A small problem with a complex integral

Hi...

I have an integral over a contour. The contour is a semicircle with vanishing radius around the origin and situated in the upper half plane.

The integrand is $$\frac{(lnx)^2}{1+x^2}$$.

The integral is supposed be zero.

I don't see how. Taking the modulus and letting the radius go to zero, I find that the denominator goes to 1 and the numerator is of the form $$ln(r^2)+\theta^2$$ with r going to zero.

Can anybody tell me what I might be missing?
