[pstricks] help

[Christophe Jorssen]

Hello,

Try with t instead of x (for parametric plot). In addition, you have to zoom
in. Try to change the definition of your function.

    \psline[linewidth=2pt,linecolor=blue](-5,2)(5,-2)
    \psset{unit=100}
    \parametricPlot[linecolor=green,linewidth=2pt]{1}{50}{%
      1*EXP(-6*t)*COS(t)+1*EXP(-6*t)*SIN(t)}{%
      1*EXP(-6*t)*(COS(t)-SIN(t))+1*EXP(-6*t)*(COS(t)+SIN(t))} %%% SIN not

Try to be more specific when writing the subject of your mail : it's easier
later to browse the achive of the list.
