FYI, the interface to Maxima changed in 4.7.1.alpha0 IIRC, so you
could also try one of the more recent alphas available at:

Hi
Thanks for the help re distributions.
My sage version is 4.7 as I downloaded a new version two days ago to

Dear Nigel,
There are two questions here.
1) How to get distributions in Sage.

The second one is harder than the first.But if your Sage is not

There are several ways to do this.
sage: maxima_console()
gives you a fully functioning version of Maxima, just as if you
downloaded it yourself.
Or you can use Maxima one thing at a time:
sage: from sage.calculus.calculus import maxima
sage: maxima.eval('integrate(cos(x),x)')
'sin(x)'
Usuall
Does this help?
sage: f = maxima("x^2-1")
sage: type(f)
sage: ff = f.sage()
sage: type(ff)
sage: ff.factor()
(x - 1)*(x + 1)

JSmath is basically a bunch of javacript routines that takes latex

Sage prefers methods to properties:

Using
z = exp(I*r*cos(theta)).real()
makes your parametric_plot3d work, too.
