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.

\documentclass{article}
\usepackage{pstricks}
\usepackage{pstricks-add}
\usepackage{pst-plot}
\psset{unit=3cm}
\begin{document}
  \psset{plotpoints=500}
  \begin{psgraph}(-1,-1)(1,1){5cm}{5cm}
    \psparametricplot{0}{360}
    {2 t mul sin 3 t mul cos}
    %sin(2t),cos(3t)
  \end{psgraph}
\end{document}
