[sage-support] quick way to factor integer coefficients of a polynomial?
Is there a quick way to factor the coefficients of a polynomial over the integers in Sage? For example, given x^2+9, I would like to rewrite it as x^2+3^2. I can see a slow way to do this (iterate over poly.factor_list(), extract coefficients, factor, rebuild the polynomial). But perhaps there is a shortcut built into Sage? --Ursula. -- You received this message because you are subscribed to the Google Groups sage-support group.

[sage-support] Plotting a q analogue function as a challenge?
Hello everyone: I'm currently trying to get support from my professors in order for our school to move from Mathematica to Sage Math. One of them challenged me to simply plot the q-gamma function on sage math, which he does on Mathematica simply by calling on the QGamma function. Here is some information about it: http://mathworld.wolfram.com/q-GammaFunction.html My problem is, I don't actually know that much about the q-gamma function, or really much about the gamma function. But, I don't want to let him down, though he seemed very doubtful that Sage would be able to do it. I was looking for the q-gamma function on Sage/maxima but I couldn't find anything that fit what I was looking for. I'm hoping that maybe I just don't know the name or the format for how it's done outside of Mathematica? To be honest, I'm fairly new to Sage as well. I'm sorry if I'm asking in the wrong place, it's because I simply don't know where to ask. If there's a better place for me to ask this, I would be happy to ask there! Thanks for your help. I'm really hoping that I can get our college to support Sage :) -- You received this message because you are subscribed to the Google Groups sage-support group.

This is implemented in sympy, which is included with sage, according to google. I haven't tried it.

Re: [sage-support] Plotting a q analogue function as a challenge?
While qgamma isn't a native function, there's a qgamma implementation in mpmath, one of the libraries included in Sage, so: from mpmath import qgamma plot(lambda x: qgamma(4,x), (x, 2, 10)) should give you a plot of gamma_(q=4).

Or rather, how do I go about calling x later? Also, what is the best way for me to find functions like this, whose implementation I don't know in Sage?

[sage-support] Re: Sage error HELP
You wrote x = (-5,5), and then you wanted to plot x^n, which is the same as (-5,5)^n. What were you intending with that? I'm assuming you wanted the plots of x^n for x = -5 to x=5?
