This is strange: sage: x, y =var('x y') sage: foo = 1/2*(x^3*y + 2*x + sqrt(x^6*y^2 + x^6 + 2*x^5 - 7*x^4 + 6*x^3 - 2*(x^6 + x^5 - 2*x^4 + x^3)*y + 2*x^2 - 4*x + 1) - x^3 - x^2 - 1)/(x^3 - x^2) sage: foo.taylor(x,0,5) 3*(3*y + 4)*x^5 + 3*(y + 2)*x^4 + (y + 3)*x^3 + 2*x^2 + x + 1 Okay, but if I

However, when I look at the difference between foo and foo.full_simplify(), all I see is that the square root gets factored and split into two: sqrt(x^6*y^2 + x^6 + 2*x^5 - 7*x^4 + 6*x^3 - 2*(x^6 + x^5 - 2*x^4 + x^3)*y + 2*x^2 - 4*x + 1) becomes, after full_simplify(), sqrt(x^3*y - x^3 +

I want to fix axes and change point-of-view.  Is this possible? Recently, I managed to find the camera position from the moveto command [1]. One way to do what you want would be to do the converse : find the moveto command from the desired camera position. This would give a solution once Jmol is

Well on top of Burcin's answer and I should add a disclaimer I am working here: http://www.ucsc.canterbury.ac.nz/ as a support person, so I feel for you. I am currently doing installs on power7 hardware from IBM and I want to use a vocabulary that is wholly inappropriate for a public forum to

Hi Burcin and Francois, Yes, I'd be willing to use an existing linux package manager rather than the spkg system, particularly if sage were on a path to the same system. I think it's important to support the 'ecosystem' sage has built. The problem of system and vendor supplied compilers and

Hi, I know Dag, we have had that conversation together in the past on sage-devel. I guess we should sit on that one along with my partner in crime Christopher. Francois -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to
