Evaluate the three-dimensional divergence V v for each of the following vectors: (a) v = (b) v = kxx, (c) v = kyi. We know that V v represents the net outward flow associated with v. In those cases where you found V v = 0, make a simple sketch to illustrate that the outward flow is zero; in those cases where you found V v 0, make a sketch to show why and whether the outflow is positive or negative.
