The first thing you should do is use properties of logarithms to write the integrand as . then change to polar coordinates so that and . The integral become . Can you do that?

I got the answer

Is it correct? - Aug 19th 2013, 12:38 AMProve ItRe: Double Integral
What are your bounds? Or what is your region you're integrating over?

ProveIt: The final integral has both x and y in it, as well as two "constants of integration" so there are no bounds- this is an "indefinite integral".

kjchauhan, I have not calculated it myself but that looks good.
