[sage-support] Re: Fwd: elliptic curve trace problem in SAGE

2008-04-07 Thread John Cremona
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,

[sage-support] Re: Fwd: elliptic curve trace problem in SAGE

2008-04-07 Thread John Cremona
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

[sage-support] code to find roots no longer works

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.y = PolynomialRing(RDF) sage: # Let y be x^(1/9). sage: f = y + RDF(2^(8/9) -

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.y = PolynomialRing(RDF) sage: # Let y be x^(1/9). sage: f = y +

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)

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:
