I´m trying to transform the integral:
I need to transform it to an integral that goes from 0 to 1 in order to apply the algorithm of Montecarlo I implemented. I´m comfortable applying the identities on single integrals, but I don´t really know how to apply the following identities to a double integral.
I investigated on books and found this hint, but I still don´t understand how to use it on a double integral. Can anyone help me?
