1. The divergence of a second-order tensor is a vector expressed as

Find the expressions for the components of divB in Cartesian, cylindrical, and spherical coordinates.

2. The stress tensor for a Newtonian incompressible fluid is given by

where p is the pressure,
 is the fluid viscosity, and the
 i are components of the velocity vector. Find expressions for components of ij and div in Cartesian and cylindrical coordinates.
