>What is the problem with 'ParametricPlot'?
Posted:
Aug 21, 1996 2:03 AM


I input the followings: x={Sin[t]}^3 y={Cos[t]}^3 ParametricPlot[{x, y}, {t, 0, Pi/2}]
And got the following outputs: ParametricPlot::ppcom: Function x cannot be compiled; plotting will proceed with the uncompiled function. ParametricPlot::ppcom: Function y cannot be compiled; plotting will proceed with the uncompiled function. ParametricPlot::pptr: x does not evaluate to a pair of real numbers at t = 0.. ParametricPlot::pptr: x does not evaluate to a pair of real numbers at t = 0.0654498. ParametricPlot::pptr: x does not evaluate to a pair of real numbers at t = 0.1309. General::stop: Further output of ParametricPlot::pptr will be suppressed during this calculation.
Can anyone tell me what is wrong? Thanks in advance!!
