    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?

    Try using polar coordinates. That should make it easier.
