RE: ParametricPlot


See The Mathematica Book Section 2.5.5 and try:
ParametricPlot[Evaluate[eight[t]],{t,0,2 Pi}]

Hope this helps,

I have the following defintion in Mathematica notebook (version 3.01 for
Mac):

eight[t_]:={Sin[t],Sin[t] Cos[t]}

Trying to plot this by executing

ParametricPlot[eight[t],{t,0,2 Pi}];

produces the right graphic but also an warning:

ParametricPlot::"ppcom": "Function eight[t] cannot be compiled; plotting
will proceed with the uncompiled function."

What is wrong ?
