![]() ![]()
This feature is a wonderful way to understand exactly how the equation represents the function. In the example above, X=T-asin(T), Y=b-cos(T), a click and drag gives you the b handle, and lets you drag the function up and down. Click and drag another place on the curve and you get the a handle to change the shape of the curve. ![]() Notice the Variable toolbox displays the changing values as you move the handles.
