This is the question that has been given in an exam some years ago, and this is the solution part that I do not quite comprehend.
I cannot understand why you have partial derivative of g with respect to x and y, because if you use their hint and take u and v as they suggest, then you would have the partial derivatives with respect to u and v, not x and y.
