CrossProduct

CrossProduct[v1, v2]
gives the cross product of the two 3-vectors v1, v2 in the default coordinate system.
CrossProduct[v1, v2, coordsys]
gives the cross product of v1 and v2 in the coordinate system coordsys.
  • CrossProduct[v1, v2, coordsys] is computed by converting v1 and v2 to Cartesian coordinates, forming the cross product, and then converting back from Cartesian coordinates.
