A spiral is a curve formed by a point revolving around a fixed axis at an ever-increasing distance. It can be defined by a mathematical function which relates the distance of a point from its origin to the angle at which it is rotated. Some common spirals include the spiral of Archimedes and the hyperbolic spiral. Another type of spiral, called a logarithmic spiral, is found in many instances in nature.

Characteristics of a spiral

A spiral is a function which relates the distance of a point from the origin to its angle with the positive x axis. The equation for a spiral is typically given in terms of its polar coordinates. The polar coordinate system is another way in which points on a graph can be located. In the rectangular coordinate system, each point is defined by its x and y distance from the origin.
