For more examples, see the help screens. The commands `ParamPlot`
and `ParamPlot3D` are analagous to the `plot` and `
spacecurve` commands you used last term. Both `ParamPlot` and `
ParamPlot3D` will take a vector or a list of functions as their first
argument. Don't forget to load the `CalcP` package if you have not
already done so.

> VDiff(g(t),t);

> VDiff(g(t),t,t);

> VPlot(f(t),t=-2..2);

> VPlot(g(t),t=0..4*Pi);

> VPlot(h(t),t=0..2*Pi);

> ParamPlot(h(t),t=0..2*Pi);

> ParamPlot3D(g(t),t=0..4*Pi);

> VMag(h(t));

The `Speed` function can either give the speed at a fixed
value of *t*, or give the speed as a vector expression involving
*t*. See the examples below.

> Speed(f(t),t=1);

> Speed(f(t),t);

> Speed(g(t),t);
