Operations on vectors, Electrical Engineering

Assignment Help:

Can add vectors using the parallelogram rule

Can multiply a vector by a scalar

           - result is a parallel vector

                       • length is scaled

                       • direction unchanged

                       • example: multiply particle's velocity vector by its mass, gives particle's momentum vector

Can combine two vectors using:

            - Scalar product (also called dot product or inner product

            - Vector product (also called cross product)

Can multiply a vector by a matrix
