Question: (a) Find the flux of the given vector field out of a cube in the first octant with edge length c, one corner at the origin and edges along the axes.
(b) Use your answer to part (a) to find div F→ at the origin using the geometric definition.
(c) Compute div F→ at the origin using partial derivatives.
F→ = 2i→ + yj→ + 3k→
