Vectors - Analytic expression of cross product

  • Recall the definition of a vector.
  • Introduction to cross product.
  • Cross product of two vectors in terms of their components.
  • Formula for the cross product of two vectors in 3-dimensional space.
  • Example: Find the cross product of vectors A = (2, 3, -1) and B = (-4, 1, 5).
  • Steps to calculate the cross product.
  • Solution: The cross product of A and B is (16, -18, 14).
  • Properties of cross product.
  • Example: Show that A x B is orthogonal to both A and B.
