Final comment - are both related to
sage: parametric_plot((0,t),0,1)
not working, which is consistent with
sage: plot(1)
not returning a horizontal line, but (sort of) inconsistent with
sage: plot(sin)
returning a curve, since Integer(1) is not callable symbolically?
Sorry for the self-responses,
To follow up, I should point out the problem seems to be in
parametric_plot and the pure imaginary points like exp(i*pi/2)
specifically, as
sage: parametric_plot( (real(x*exp(i*pi/2)),imag(x*exp(i*pi/2))),0,10)
causes the same problem, even though
sage: [(float(real(x*exp(i*pi/2))),float(imag(x*ex
In notebook on sagemath.org, the strange behavior reported at the end
of this post occurs with parametric plots. It isn't clear to me
whether this is some mistake of mine in trying to plot complex
parametric curves, or a bug in plot related to previous subscripting
issues. Using C(pi/5,r) instea

Is there a command for SAGE to write an element of a group in terms of

Dear Mike,
Thank you very much for your explanation and solution. The amended code
now works perfectly. You made my day!
Best regards,

Hi,
The issue is that .roots() now returns tuples with the root and its
multiplicity. You can see this if you look at v. You need to select
the 0th entry of the tuple to raise to a power.
sage: RDF = RealDoubleField()
sage: R. = PolynomialRing(RDF)
sage: # Let y be x^(1/9).
sage: f = y + RDF(2
Last September I asked how to use SAGE to find the roots of
f = x^(1/9) + (2^(8/9) - 2^(1/9))*(x - 1) - x^(8/9).
William Stein then kindly offered the following code:
sage: RDF = RealDoubleField()
sage: R. = PolynomialRing(RDF)
sage: # Let y be x^(1/9).
sage: f = y + RDF(2^(8/9) - 2^(1/9))*(y^9-1)
I have posted a patch for this on trac #2849. The bug would strike
for any curve with j=0 (=1728) defined over GF(3^d) for odd d.
Assuming someone reviews this positively it will get into sage-3.0.
It is also likely that by then there will be much better support for
the cases j=0 and j=1728 anyw
I'll fix this as it is my code.
Note that this curve has j=0 and the cases of j=0, 1728 were not
implemented with any efficiency (or, it seems correctness), but that I
am half-way through doing that.
In the meantime I'll try to put in a quick patch to correct what's
wrong here. First step, I'll

Hector told me (in a separate email) about DOLFIN

which is built on numpy. Although I had trouble installing it,
I'm wondering if anyone else on this list has been able to try it out?
