The surface is hemisphere with y = 0 plane being the boundary, though the question should have been more clear on that.Similarly, Stokes Theorem is useful when the aim is to determine the line integral around a closed curve without resorting to a direct calculation. As Sal discusses in his video, Green's theorem is a special case of Stokes Theorem. By applying Stokes Theorem to a closed curve that lies strictly on the xy plane, one immediately derives Green ...

Remark: By a limiting argument and the mean value theorem for surface in-tegrals, this leads to the interpretation of the curl as the infinitesimal density of circulation per unit area, directed along the axis of rotation given by the direction of the curl. The usual proof of Stokes’ theorem considers a patch of surface given by the
