Measure Cross Product
The cross product returns a vector perpendicular to both input vectors.
Formula: a × b = (a₂b₃−a₃b₂, a₃b₁−a₁b₃, a₁b₂−a₂b₁)
The formula links the named physical or geometric quantities directly, so each input has a defined role in the result.
Checking the dimensions of both sides is a useful way to catch a wrong unit or misplaced value.
