- Anti-commutative $$ u \times v = -(v \times u) $$
- On self $$ a \times a = 0 $$
The magnitude of the cross product of two vectors can be found with $$||u \times v|| = ||u|| * ||v|| * \sin(\theta)$$
The magnitude of the cross product is equal to the
The magnitude of the cross product is equal to the area of the parallelogram formed with two adjacent sides as the vectors.
### Triple Scalar Product
Find the Determinant of:
$$u * (v \times w) = \begin{vmatrix} u_{1} && u_{2} && u_{3} \\ u_{1} && u_{2} && u_{3} \\ u_{1} && u_{2} && u_{3} \end{vmatrix}$$
The triple scalar product can also be found by finding the cross product of $v$ and $w$ and then taking the dot product of the resulting vector and $u$.
$$u * (v \times w) = (u \times v) * w $$
The triple scalar product is equal to the volume of the parallelpiped where each vector represents one adjacent edge.
