DotProduct
As of version 9.0, vector analysis functionality is built into Mathematica 
gives the dot product of the two 3-vectors 
, 
in the default coordinate system.
gives the dot product of

, 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.
