# DotProduct

As of Version 9.0, vector analysis functionality is built into the Wolfram Language

gives the dot product of the two 3-vectors , in the default coordinate system.

gives the dot product of and in the coordinate system coordsys.

## DetailsDetails

• 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.
