[pstricks] Dumb question -- asked before?

[Hubert Lam]

Hi all

I'm sure I've asked this before but I can't seem to find it again in the archives.

I remember some years ago I asked about \psplot doing some cube root function, and it would fail at $x = 0$.

What was the workaround for this?


Reason:  I'm trying to sketch $x^3 + y^3 = 1$ but without \psplotimp which gives of course, a much poorer image than if I were to parameterise it to

$x = t^{\frac{1}{3}}$ and $y = (1- t)^{\frac{1}{3}}$.

Many thanks

Hubert
