Show that the vector field F(x, y, z) = (-3y cos(2x), 2x sin(-3y), 0) is not a gradient vector field by computing its curl. How does this show what you intended? curl(F) VF =

Show that the vector field F(x, y, z) = (2y cos(-3x), –3x sin(2y), 0) is not a gradient vector field by computing its curl. How does this show what you intended? curl(F) = V x F =( 0 ).
