Hello, first time posting here. We all know the nice way to integrate y = exp(ar^2) using polar coordinates, right? What about y = exp(r^2/(2*(a+bsin(n*theta  phi))^2) Obviously I am trying to make the denominator in the exponential argument look similar to the standard deviation (sigma) of the standard Gaussian y = exp(r^2/(2*sigma^2)). Perhaps I should write the sinusoid term in the numerator (similar to the ar^2)? If anyone knows how to get the normalization factor for this form of Gaussian, that'd be great to see! Cheers
