Heya all

Firstly thanks in advance. I have a problem in my calculas course, which I was hoping that you guys would be able to help me with.

The question is:

Integrate $\displaystyle \frac{\ln(x^2+y^2)}{x^2+y^2}$ over the region between the circles $\displaystyle x^2 +y^2=1$ and $\displaystyle x^2+y^2=e^2$.

Could someone give me a pointer on where to start please?
