What is the relationship between polar coordinates, vectors, complex numbers

There is also a connection between multiplication of complex numbers and polar coordinates. As usual, polar coordinates of a point ( x , y ) in the plane are defined as ( r , θ ) where r is the length of the vector ( x , y ) and θ is the angle this vector makes with the positive x axis.
