[sage-support] Re: plots in 3d are not published?
Thanks Jason for everything you are doing. I would really appreciate it if you would write here when we can publish 3d plots in sagenb. Thanks kcrisman for the confirm. At least I now know that I am not doing it wrong. Best Linda On Jan 18, 1:36 am, kcrisman kcris...@gmail.com wrote: BTW: I cannot get mesh=True, dots=True or plot_points=[n,m] to work with plot3d. I'm not sure what is going on there, and can't look at it right now. Sadly, this is (at least)http://trac.sagemath.org/sage_trac/ticket/9708 and has been open for a while :( -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
[sage-support] Minor issue: Polynomial simplify, square roots
After saying R.t = PolynomialRing(QQ) both of these works: expand ( (t-(5-sqrt(7))) * (t-(5+sqrt(7))) ) expand ( (t-(5-sqrt(7))) * (t-(5+sqrt(7))) ) and I got t^2 - 10*t + 18 and t^2 - 4*t + 1 as expected. However, expand ( (t-(2-sqrt(3))) * (t-(2+sqrt(3))) * (t-(5-sqrt(7))) * (t-(5+sqrt(7))) ) does not work in a similar way. If I put .simplify_full() at the end of the expression, I got simplified answer. What is logic behind this? -- Jori Mäntysalo -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Thanks. Given that, here's the sagenb (4.7.2) version, showing the bug
(wrong when t is negative real):
sage: t=var('t')
sage: f=(1/2)*log(2*t)+(1/2)*log(1/t)
sage: f.full_simplify()
1/2*log(2)
I created a ticket for this here:
http://trac.sagemath.org/sage_trac/ticket/12322
Thanks for the example!

[sage-support] max plus polyhedra and tropical algebra
hi, I don't think there is any support for these topics in Sage -- any plan to consider them ?

Thanks What does max plus polyhedra and tropical algebra mean? I've heard of max, plus, and polyhedra, which are all very well supported in Sage, and I've heard of tropical geometry, which has some support via the standard gfan package. -- William -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -- William Stein Professor of Mathematics University of Washington http://wstein.org -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
