# Describe Equation of Curves

The parametric equation is simply a way of define a relation using with the help of parameter. For example a curve is given by x = x(t), y = y(t) is said to be a parametrically defined curve and the functions of the curve is x = x(t) and y = y(t) are said to be the parametric equation for the curve. In the below sections, learn this concept of parametric curve equation in detail.
