# Thread: Integration of Logarithmic Function

1. ## Integration of Logarithmic Function

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

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

2. Try using polar coordinates. That should make it easier.
