VECTOR ANALYSIS PACKAGE SYMBOL

Div

Div[f]
gives the divergence,

, of the vector field f in the default coordinate system.

gives the divergence of f in the coordinate system coordsys.

The vector field f should be a 3-element list where each element is a function of the coordinates of the appropriate coordinate system.
