thlem ti: For the vector function: F = (y: x2)x +(2xy JOE}. + 32:12 a) Evaluate the ux of this vector function through all six sides of a cube with one corner at the origin of the coordinate system and each side of length 2. h) Calculate the divergence of this vector function and show that integrating the divergence over the volume of the cylinder gives the same answer as in part {a}
