polar coordinates

plural noun Geometry

1A pair of coordinates locating the position of a point in a plane, the first being the length of the straight line (r) connecting the point to the origin, and the second the angle (θ) made by this line with a fixed line.Cartesian and polar coordinates are great tools in the analytic geometry of the plane....

It was based on polar coordinates whereas earlier instruments were based on cartesian coordinates.
On page 149, Pesic mentions de Moivre's discovery of the formula (cos [theta] + i sin [theta]) n = cos n [theta] + i sin n [theta] and implies that to prove it one needs to think about complex numbers in polar coordinates.

1.1The coordinates in a three-dimensional extension of polar coordinates.Since the profile is a curved shape, it's much easier mathematically to use what are known as as polar coordinates.
