Products of Vectors

There are two kinds of product of two vectors. One, called the scalar product(or dot product or inner product), gives a result which is a scalar; the other, called the vector product(or cross product or outer product), gives a vector answer.


Scalar Product

We define the scalar product of two vectors A and B (written A.B)

we draw the two vectors from a common point.The angle between their directions is
