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
  • [[3b1b essence]]
