[sage-support] Setting the bounding box on plot3d

Is there any way for the user to set the bounding box on plot3d? The basic idea is I don't want the full z-values for the function and would like to crop some of them off. The best I've come up with so far without hunting through source files is: y=var('y') f=lambda x,y: min(x^2+y^2,4); plot3d(

[sage-support] aspect_ratio in 3d

I don't understand aspect_ratio for 3d plots, or maybe there are bugs. If I do (from the notebook interface) sage: var('x y') sage: Q = plot3d(sin(x+y), (-3,3), (-2,2)) sage: Q.show() then I get a nice picture, with a labeled frame showing x going from -3 to 3, y from -2 to 2, z from -1 to 1. Th

This is great, this is actually how I initially hoped it could be done. And yes - I am quite new to SAGE. It's though still a bit messy, since when I in F2 request a random_element() I will only get "1" or "0". /David On Sep 29, 9:12 pm, "Justin C. Walker" <[EMAIL PROTECTED]> wrote: > On Sep

Thank you David. This seems to work just fine, though a bit of a roundabout - I agree. I do not understand why sage doesn't have a command just letting you expand a Galois field with a arbitrary expansion degree, in my case 4. /David --~--~-~--~~~---~--~~ To post

Thank you for you answer Justin and I should also apologize for my badly formulated question but you understood it correctly. I just can't get SAGE to eat the line you write f=x^2+x+F1(1), it complains with: TypeError: unsupported operand parent(s) for '+': 'Symbolic Ring' and 'Finite Field in a

Here's an alternative approach: sage: F1 = GF(2^7,'a'); F2 = GF(2^28,'b') # different names for legibility sage: F1.gen().minpoly().roots(F2) [ long list ] sage: g = F1.gen().minpoly().roots(F2)[0][0] sage: phi = Hom(F1, F2)(g) This is a bit roundabout, but it works. Unfortunately at present you
