## Homework Statement

During my calculation of hydrogen atom perturbation, I need to integral below in cartesian coordinate. It is given that below integral can be transformed.

## Homework Equations

Anyone could help to see what will the transformed integral in polar coordinate if the left-hand-side integral were changed to r*x^2*exp(-r) instead of x^2*exp(-r).

Thanks.
