Evaluate the line integral in Stokes' Theorem to evaluate the surface integral (V XF) . n dS. Assume that n points in an upward direction. S F = (x+ y,y+ z,z + x) ; S is the tilted disk enclosed by r(t) = (4 cost, 6 sin t, 120 cost) . ..... Find the value of the surface integral. SS ( V XF) . n ds = S (Type an exact answer, using it as needed.)
