Check the divergence theorem for the vector function A = s2 Sin[φ]s^ + 2s2 Cos[φ]φ^ + 3szSin[φ]z^ (cylindrical coordinates) using the volume of a half-cylinder as shown in the figure. The base of the half cylinder is in the x−y plane (z = 0) and the vertical plane is in the x−z plane (y = 0). The radius of the cylinder is R and the height is L.
