Outer product
If a triangle
in space is faced from the opposite side of origin 
and its vertices follow a counterclockwise order 
, 
is denominated as a right-hand system.
is the surface of the parallelogram whose sides are 
.Let
be a unit vector perpendicular to both 
that forms a right-hand system.The outer product is expressed as
and is defined as:
.
Property 1
- Commutative law
- Distributive law
- Associative law
Property 2
- For unit vectors
of an orthogonal coordinate system,
- If
, then
