polárkoordinátarendszer
The polárkoordinátarendszer, or polar coordinate system, is a two-dimensional coordinate system where each point is identified by a distance from a central point and an angle with respect to a reference direction. The central point is called the pole, and the reference direction is called the polar axis. A point in the polar coordinate system is represented by an ordered pair (r, θ), where 'r' is the radial distance from the pole and 'θ' is the angle measured counterclockwise from the polar axis.
The radial coordinate 'r' represents the distance of the point from the pole. It can be any
The polar coordinate system is particularly useful for describing phenomena that exhibit radial symmetry, such as
