Radius Vector 

The radius vector of an arbitrary point in space is the vector drawn to the point from some fixed point, which is called the pole. If the origin of a rectangular Cartesian coordinate system is selected as the pole, then the projections of the radius vector of a point M on the coordinate axes coincide with the coordinates of M.
