You have only to enter two functions f (t) and g(t) defining the parametric curve, with ranges of variation for t, x, y. You will receive as reply an animated sequence showing the curve with a moving point corresponding to the variation of the parameter t. This variation of t is shown by a bar at the bottom of the figure, synchronized with the point on the curve.
Some examples of parametric curves are at your disposal.
