[sage-support] Re: Bug with two Latex().eval() in Sage Notebook

2012-04-07 Thread Pedro Cruz
Possible hint: I did not check Latex().eval() code but probably it uses temporary random filenames to store the object to the file and then to compile it and that's why there is no fixed order at output (maybe filename alphabetic order). Pedro Quinta-feira, 5 de Abril de 2012 17:32:59 UTC+1,

[sage-support] Subfields of finite fields

2012-04-07 Thread Rob Beezer
Is there a way to build subfields of finite fields that will behave as subfields? For example, a finite field of order 3^6 will have proper subfields of order 3^1, 3^2, 3^3. The first is not too interesting and can be recovered with the .prime_subfield() method. I can easily build the set of

Ack! I found this thread while looking for progress on 3D animation, and didn't notice that it's *two years old*. Anyway, I am indeed thinking of working on this. On Saturday, April 7, 2012 4:41:43 PM UTC-4, Niles wrote: > > I've been thinking about working on basic 3D animations for Sage; I

I've been thinking about working on basic 3D animations for Sage; I haven't yet found an open ticket either. On AskSage, I gave an example showing how to hack the current animation functionality to animate 3D plots: http://ask.sagemath.org/question/1275/interact-3d-plotpolyhedron?answer=1999#19

[sage-support] to_poly_solve inconsistency for periodic functions

2012-04-07 Thread Duc Trung Ha
Hola, I was wondering about following eerie behavior of "solve" function: On the one hand, "force" value of "to_poly_solve" option seems to be more powerful as for periodicity of solutions: sage: solve(tan(x)==1,x,to_poly_solve=True) [x == 1

Thanks a lot, Dmitrii! It works for me now. (Actually for quite some time, but now I can happily report, that compared to cvxopt that I was using before, using csdp is about 10-times faster!) I didn't know about sage -sh , that is a very useful trick (perhaps it should be documented more, or
