Gregory Bard of the University of Wisconsin, Stout has the following
solution for the always-vexing cube-root plotting issue.
{{{
def cuberoot(x):
return sign(x)*((x*sign(x))^(1/3))
plot( cuberoot(x), -4, 4)
}}}
Probably just adding `plot(sign(x)*(x*sign(x))^(1/3))` or something to
[http://www.sagemath.org/doc/reference/sage/plot/plot.html the plot doc]
(search for 'cube') as another example would be sufficient for now. I
don't know whether we would want to add a whole new function, since we'd
then need one for every odd integer root function... or? Maybe that would
be ok, `real_nth_root()`...
Putting under documentation component, feel free to change if graphics is
more appropriate.
