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.
