Div
Div[
f
]
gives the divergence,
f
, of the vector field
f
in the default coordinate system.
Div[
f
,
coordsys
]
gives the divergence of
f
in the coordinate system
coordsys
.
MORE INFORMATION
To use
Div
, you first need to load the
Vector Analysis Package
using
Needs
["VectorAnalysis`"]
.
The vector field
f
should be a 3-element list where each element is a function of the coordinates of the appropriate coordinate system.
