1. The problem statement, all variables and given/known data Let D be the set of points (x,y) in R^2 for which 0 is ≤ x ≤ 1 and 0 ≤ y ≤ 1. Find a function g: R^2 --> R for which: ∫_0^1 ∫_0^1 h(x,y)dxdy = ∫_0^1∫_0^1 h(y^5, x^3) * g(x,y)dxdy is true for all functions h: D--> R integrable over D In the question before this I was asked to find a jacobi matrix and determinant for f(x,y) = (y^5,x^3) I found that the determinant is -15y^4x^3 2. Relevant equations 3. The attempt at a solution ∬_D f(x,y)dxdy= ∬_S g(v^5,u^3) * -15y^4x^2 Is this my final result? If not, can I get some help on how to go on?
