# Parametric Equation of a Circle Calculator

Parametric equation are equations that express a set of quantities as explicit functions of a number of independent variables, known as parameters. In simple, a parametric equations are a method of defining a relation using parameters. A Parametric equation of a circle is the coordinates of a point on the circle in terms of a single variable θ. Parametric equations are easiest way to represent curves and surfaces.

This online analytical calculator helps you to find the parametric equation of a circle using the radius.
