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.
