  1. a a b Vectors C4 Scalar Product The scalar (or dot) product is a way of combining two vectors that results in a useful scalar value.

  2. a a b ? ? Vector Product Def. Vector Product The vector (or cross) product is a way of combining two vectors that results in a useful vector. Right-hand rule. Screwdriver undoing a screw.

  3. Vector Product There was an easy alternate way to find the scalar product, found by considering unit vectors. There must be an easy way to find the cross product too. Idea
