7. If F(x, y, z) = (-xy)i (xz)j + (2yz) k and C is the closed triangular curve oriented counterclockwise around the plane y+z=2 from z=0 to z = 3 in the first octant viewed from above, use Stoke's theorem to evaluate fF.dr.

If F(x, y, z)= tanzi+(+2) j+zsiny k anda is the portion of the cone z = 2-√² + y² above the ry-plane oriented so that the unit normal vector n points to the outside of the cone, use Stokes' theorem to evaluate ff,(V x F).nds.
