Generalised vector products and metrical trigonometry of a tetrahedron
Gennady A Notowidigdo, Norman J Wildberger
We study the general rational trigonometry of a tetrahedron, based on quadrances, spreads and solid spreads, using vector products associated to an arbitrary symmetric bilinear for…

Generalised vector products in three-dimensional geometry
Gennady A Notowidigdo, Norman J Wildberger
In three-dimensional Euclidean geometry, the scalar product produces a number associated to two vectors, while the vector product computes a vector perpendicular to them. These are…
