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.
There is a tutorial that draws polar graphs at www.
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.
