In mathematics, the polar coordinate system specifies a given point in a plane by using a distance and an angle as its two coordinates. These are. the point's direction from the pole relative to the direction of the polar axis, a ray drawn from the pole.

4 days ago · The polar coordinates r (the radial coordinate) and theta (the angular coordinate, often called the polar angle) are defined in terms of Cartesian coordinates by x = rcostheta (1) y = rsintheta, (2) where r is the radial distance from the origin, …

We engineered and designed the next generation PolarCool. The number one featured request, X-Large reservoir, we responded with the PolarCool Pro! The PolarCool Pro has a rotationally molded reservoir 3x times larger than our original 36" PC fan. This larger reservoir allows for running up to three times longer without a direct water supply!
