Cross Product

Make vector as columns of matrix
Get the determinant
Sign defines the direction of the cross product
True cross product
- Combines 2 vectors into a third vector
- perpendicular to the original plane
- Direction of cross product is by RH rule
- fill in basis vectors as first column to calculate the cross product
Geometrically – forms a vector perpendicular to the 2 vectors with length as area of the parallelogram
