what is this system about?
A two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction
Polar coordinate system
In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction
when are polar coordinates used in real life They are used often in navigation as the destination or direction of travel can be given as an angle and distance from the object being considered

Polar coordinate system [SEP] Introduction
In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point (analogous to the origin of a Cartesian coordinate system) is called the "pole", and the ray from the pole in the reference direction is the "polar axis". The distance from the pole is called the "radial coordinate", "radial distance" or simply "radius", and the angle is called the "angular coordinate", "polar angle", or "azimuth". The radial coordinate is often denoted by "r" or "ρ", and the angular coordinate by "φ", "θ", or "t".
