- Evaluate ∬Sz+3y−x2dS where S is the portion of z=2−3y+x2 that lies over the triangle in the xy-plane with vertices (0,0), (2,0) and (2,−4). Solution
- Evaluate ∬S40ydS where S is the portion of y=3x2+3z2 that lies behind y=6. Solution
- Evaluate ∬S2ydS where S is the portion of y2+z2=4 between x=0 and x=3−z. Solution
- Evaluate ∬SxzdS where S is the portion of the sphere of radius 3 with x≤0, y≥0 and z≥0. Solution
- Evaluate ∬Syz+4xydS where S is the surface of the solid bounded by 4x+2y+z=8, z=0, y=0 and x=0. Note that all four surfaces of this solid are included in S. Solution
- Evaluate ∬Sx−zdS where S is the surface of the solid bounded by x2+y2=4, z=x−3, and z=x+2. Note that all three surfaces of this solid are included in S. Solution
