Parametric Equation

Graphing Page



The goal behind this page is to give the reader an introduction to plotting parametric equations.

Just a reminder of the definition of parametric equations.



A definition of Parametric Equations :

Let f and g be two functions defined on an interval I. The relation of all ordered pairs (f(t),g(t)) for t in I is called curve C. The equations :


x = f ( t ) and y = g ( t ) ( for t in I )


are called parametric equations for C. and the variable t is called the parameter.




To plot a set of parametric equations by hand you need to follow the steps below :



An easier way to graph parametric equations is using a graphing utility.

If you have access to a graphing calculator, plotting parametric equations is very easy, just follow the steps below :
