We continue our investigation of parametric equations. Because of the complexity of the graphs of parametric equations, we will limit our investigation to the following set of equations.
Since a and b in the equation above are both 1, the equation is of the same form as the equations on the previous page. The graph is an ellipse with xintercepts 4 and 4 and yintercepts 3 and 3. Now we want to have a look at what happens when we change a and b to values other than 1. 









This class of parametric curves is called the Lissajous Curves. Click here to see an animation of these curves.
