Parametric plots

Besides the usual Cartesian coordinate plots and polar plots, Pstricks also can realize parametric plots. The command is "\psparametricplot[options]{t0}{t1}{x(t) y(t)}". "t0" and "t1" are the begin and end value of variable t. "x(t)" and "y(t)" are interpreted as the parametric plot functions.

Now we come to practice on this command.
