Let the surface S be the part of the plane 2x-y+z=3 that lies above the triangle in the xy plane that is bounded by the lines y=0, x=1 and y=x. Find the total mass of S if its density (mass per unit area) is given by
The Attempt at a Solution
Ok so i know this is a double integral. the limite will be
and f'(x)= 2, f'(y)= -1
√(f'(x) + f'(y) + 1)= √6
so my equation is
and i have a feeling I am meant to convert this into polar coordinates but how do you convert the limits to polar coordinates?
