# Parametric Equation 2-variable type (y-axis)

## Description

In mathematics, parametric equations of a curve express the coordinates of the points of the curve as functions of a variable, called a parameter. A parametric equation of the 2-variable type, to be combined with the y-axis equation of the same type gives a specific form of a curve.
