- 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
- [[3b1b essence]]
