[sage-support] Re: No sans-serif font in notebook latex entries

Hi Brian, In a notebook cell, I enter and evaluate: %latex $M^\mathsf{T}$ and get back a slanted M and a very crisp, upright superscript T. So it can be done, but this is accomplished by running a full-blown instance of TeX and creating a PNG graphic as output. $M^{\sf T}$ looks to render ide

Hi, First I'd like to say that I'm new to sage, I like it very much so far, and I am excited by its potential. The attention to documentation is especially nice. I currently have an issue with sans serif fonts in latex math entered in the notebook interface. Specifically I'm trying to get a ni

The installation instructions cover Windows but only for single users I believe. When the installation instructions cover installation of multi-user servers they only seem to address Linux. Does anyone know where I can find instructions for installing a multi-user Sage server on Windows (preferabl

Hello, I'm trying to build a "tower" of field extensions but an error occurs. This is the code: p = 0xb6408c635200288d94aa5534d459922940402af3364b031b R = GF(p) _. = PolynomialRing(R) R2. = R.extension(X^2+1, 'X') _. = PolynomialRing(R2) xi = -X + 1 R6. = R2.extension(Y^3-xi, 'Y'

[sage-support] New coefficients under a change of variables

I am new to Sage and symbolic math in general.I am trying to find the new coefficients of an equation under a change of variable.For example, if I have the equation eq == a*x + b*y and I rotate the axes (i.e. cs = cos(theta), sn = sin(theta) ) x == x1*cs + y1*sn y == -x1*sn + y1*cs I w
