OBSOLETE VECTOR ANALYSIS PACKAGE SYMBOL
DotProduct
As of version 9.0, vector analysis functionality is built into
Mathematica 
- To use
, you first need to load the Vector Analysis Package using Needs["VectorAnalysis`"].
is computed by converting 
and 
to Cartesian coordinates and then forming the dot product.
Dot product of two Cartesian vectors:
| Out[4]= |  |
Verify that a pair of vectors are orthogonal:
| Out[4]= |  |
Dot product of vectors in cylindrical coordinates:
| Out[4]= |  |
Compare with the result from conversion to Cartesian coordinates:
| Out[5]= |  |
, 
in the default coordinate system. 
and 
in the coordinate system coordsys.
