We need volunteers for peer review. The paper concerns a trigonometric relationship that exists between directions in three-dimensional space that does not exist in two-dimensional space.

3D identities (tridentities) in Euclidean 3-space.pdf

If the proof is valid, it means that direction is a scalar, in addition to being the vector that we all know and love.
