hiii. pls help me solve this question. write it neatly and understandable. need it ASAP. thx mateee... cheerssss.

a) Use Divergence Theorem to find the flux of the force field F ( x, y, z) = (x3 + 2sinx) /+(y3 -cosz) j+(23 -e*)k across the surface S of the solid bounded above by z = \\4- x2 -y and below by the xy -plane. [Hint: use spherical coordinates]
