Parametric Equations

From web research, "in mathematics, parametric equations of a curve express the coordinates of the points of the curve as functions of a variable, called a parameter. For example, are parametric equations for the unit circle, where t is the parameter. Together, these equations are called a parametric representation of the curve." Parametric equations are a set of equations that express a set of quantities as explicit functions of a number of independent variables, known as "parameters." For example, while the equation of a circle in Cartesian coordinates can be given by , one set of parametric equations for the circle are given by
