(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

trying to evaluate the double integral from 0 to infinity and 0 to infinity of [(x^2 + y^2)/1 + (x^2-y^2)^2]e^-2xy dxdy

using the coordinate transformation u=x^2-y^2 and v=2xy

2. Relevant equations

3. The attempt at a solution

so i calculated the jacobian which looks nice 4(x^2+y^2)..can see some canceling there

just can't see what the new limits will be...

thanks for any help
