Parametric Differentiation**

In mathematics, a parametric equation defines a group of quantities as functions of one or more independent variables called parameters.

Parametric equations are commonly used to express the coordinates of the points that make up a geometric object such as a curve or surface, in which case the equations are collectively called a parametric representation or parameterization of the object.

Parametric equations give us a convenient way to describe curves, or to study the position of a particle or object in two dimensions as a function of time.
