ScalarTripleProduct

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

ScalarTripleProduct[v1,v2,v3]

gives the scalar triple product of the three 3-vectors v1, v2, and v3 in the default coordinate system.

ScalarTripleProduct[v1,v2,v3,coordsys]

gives the scalar triple product of v1, v2, and v3 in the coordinate system coordsys.

Details and Options

  • To use ScalarTripleProduct, you first need to load the Vector Analysis Package using Needs["VectorAnalysis`"].
  • ScalarTripleProduct[v1,v2,v3,coordsys] is computed by converting v1, v2, and v3 to Cartesian coordinates and then forming the scalar triple product.
