let f be continuous on [0,1] and R be a triangular region with vertices (0,0), (1,0) and (0,1). Show:
the double integral over the region R of f(x+y)dxdy = the integral from 0 to 1 over u f(u)du
I recognize it is a change of variables problem but I'll be damned if I can create a set of functions u and v that yield the right jacobian. If anyone can help, its much appreciated.
