skew product, , of non-zero vectors and
The product of their moduli by the sine of the angle of positive (anti-clockwise) rotation from to :
If and (or) , then the pseudo-scalar product is assumed to be zero.
See Vector algebra.
The pseudo-scalar product of two vectors gives the length of the vector product of these two vectors.
