Consider the unit cube with vertices (corner points) (0, 0, 0), (0, 1, 0), (1, 0, 0), (1, 1, 0), (0, 0, 1), (0, 1, 1), (1, 0, 1), (1, 1, 1). Let S be the boundary of the cube minus (i.e. not including) the bottom square (the side which lies in the xy plane). Orient S with the normal which points out of the cube. Let F = <− y , x , y^2e^x . Evaluate (curl F) · dS. S Make sure you carefully compute the curl. Hint: Use Stokes’ Theorem twice to write the flux integral as an equal flux integral but over a different surface.
