With this, find the solution to the DE: f(x,y) = Z M dx = Z xy 2+3x2ydx = 1 2 x y2 +x3y +g(y) And solve for g(y): f y = x 2y +x3 +g0(y) = x3 +x y So we didn’t need g(y).

  For given (x;y), the lower bound is 0 (since the tetrahedron has base on the xy-plane), and the upper bound is the plane in question. The formula for z we get for the plane is z= 1 6 (8 2x 4y) = 1 3 (4 x 2y). We want to integral the function 1 to get volume, and dV = dxdydz.
