Dynamic Parametric Curves

Visualizing a Parametric Curves As Time Elapses

Unlike curves that are described in the form $y=f(x)$ that just give the static path of an object, parametrically described curves, $x=x(t), y = y(t)$, give the dynamic motion of an object. The visualization below shows the graph of the static curve defined parametrically, but if you click on the "Move" button, you can observe its dynamic motion by observing the dynamic motion of an ant as it travels according to the motion described by the parametrically defined path.  If you click on the Next button, it will take you to a different parametrically defined curve.

$x(t)=\sin(t), y(t)=2\sin(t), 0<t<20$

$x(t)=t^2, y(t)=t^3, -2<t<2$

$x(t)=\cos(-t), y(t)=\sin(-t), 0<t<20$

$x(t)=e^t, y(t)=e^{2t}, -2<t<1$

$x(t)=t^3-6t, y(t)=t^2-5, 0<t<3$

$x(t)=t-\sin(t), y(t)=1-\cos(t), 0<t<10$

$x(t)=2\cos(t^2), y(t)=2\sin(t^2), 0<t<8$

$x(t)=e^t\cos(8t), y(t)=e^t\sin(8t), -2<t<2$

$x(t)=\frac{1}{t}, y(t)=\frac{1}{t^2}, -4<t<4$

$x(t)=t+t^2, y(t)=t-t^2, -3<t<3$
