# Parametric equation 3-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. Parametric equation (y-axis) to be combined with a 3 Variable parametric equation gives a specific form of curve.
