A vector perpendicular to the plane containing a vector is the cross product. Because the cross product produces another vector perpendicular to the plane of the two original vectors. A unit vector is just that new vector (cross product) divided by the magnitude of the two original vectors. See pg 22 of analytical mechanics for example
