*Problem:*

Draw the graph of the parametric equations
**
x = sin**^{2}(t)

y = cos(t)
for values of **t** between **0** and **4p**.

*Visualization:*

Use the following LiveMath Notebook to explore the graph of these equations.
Click on the graph to start the animation. The red dot indicates the point
**(x(t), y(t))** for various values of **t** which are indicated
at the upper right-hand corner of the notebook. You can slow down or speed
up the animation by clicking on the box containing the phrase '6 frames/second'.
In addition, you can change the values of the constants in
the equations and see the effect on the graph.
