1. The problem statement, all variables and given/known data Take the double Integral of (xy+e^z)dS where S is the triangle with vertices (0,0,3),(1,0,2),(0,4,1). 2. Relevant equations 3. The attempt at a solution So the equation of the plane for the triangle given is z = 3 - x - (1/2)y. We plugged that Z into the z from the function given and are having a bit of trouble finding the bounds we integrate the double integral over. Help!?!
