polar coordinate system

A system of coordinates in which the location of a point is determined by its distance from a fixed point at the center of the coordinate space (called the pole), and by the measurement of the angle formed by a fixed line (the polar axis, corresponding to the x-axis in Cartesian coordinates) and a line from the pole through the given point. The polar coordinates of a point are given as (r, θ), where r is the distance of the point from the pole, and θ is the measure of the angle.

In most cases this will be from a pad of squared paper but I may have to distribute paper that has been prepared for drawing log-log, semi-log, isomorphic or polar graphs.
From this data, customers can determine, with an instantaneous polar graph, exactly where thickness variations are located on their product, the company says, adding that all types of multilayer films, whether coextruded, coated, or laminated, can be measured on the system.
Also, they can easily read their reports in formats that help them better analyze their data, such as 2-D, 3-D and polar graphs.
