6.3 Scalar Product and Vector Product

. Scalar Product and Vector Product Next we recall the scalar product and vector product of two vectors as follows. Definition . Given two vectors ˆ a i a j a k ˆ b i b j b k the scalar product (or dot product) is denoted by a b and is calculated by a b a b a b a b and the vector product (or cross product) is denoted by a , and is calculated by Note   a b is a scalar, and  is a vector.
