Product of Vectors

When two vectors and are multiplied, the result is either a scalar or a vector depending how the two vectors were multiplied. The two types of vector multiplication are:

Scalar product (or dot product) gives a scalar.
Vector product (or cross product) gives a vector.
The dot product between two vectors is defined as = |A||B|cosθ_AB ..................(1.6)
Vector product
is unit vector perpendicular to and
