In mathematics, a way of defining the
position of a point in terms of its distance
r from a fixed point (the origin) and its
angle `theta' to a fixed line or axis. The
coordinates of the point are (r,`theta').
Often the angle is measured in radians,
rather than degrees. The system is useful for
defining positions on a plane in programming
the operations of, for example,
computer-controlled cloth- and metal-cutting
machines.
