Maybe you could use QQbar instead of UCF?

I think Sage does not use the main IPython profile from ~/.ipython, but has its own copy in ~/.sage/ipython-5.0.0.

This looks like a bug in giac. The integrand that Sage passes to giac is (b^2*x^2 + a*b*x*2 + a^2)^(-3/2) * x^4 which

To answer your second question, you can put this in your init.sage file: import matplotlib.style matplotlib.style.use("

As Sage seems to overwrite part of the style, I find it easier to create the plots directly in matplotlib, especially fo

IMO, it would be better to correct the existing answer which has already been accepted. Otherwise it might encourage sim

No! This answer is not the right thing to do. It fails in all but the most basic examples because it relies on Macaulay2

This may not be perfect yet, but seems to work. This uses NumPy for numeric evaluation and SymPy for symbolic evaluation

Usually, you need a second equation to solve for two variables.

S is a nested polynomial ring, for which multiplication is very slow in Sage. It uses the Karatsuba algorithm, which I t

The __invert__ method needs to be defined with double underscores instead of single underscores. If you implement it, th

Great. This answer has just helped me a lot with a complex integral I could not solve before.

Presumably, you want to make available the partially computed results to speed up computations in the body of the functi

Nice. How long did the factorization take? This means the full list of primes for which the system A1+A2+extra has a Grö

On a second machine, with Sage installed from pacman, the computation takes only 2 minutes 40 seconds.

Yes. I reran the computation and it finished in about 6 minutes. Try to run each command of the function individually. T

Sage is not able to understand the output of Giac because the result returned by Giac contains the expression sqrt(-exp(

Even if Giac crashes and Sage does not, it is safer to restart Sage as well, just to be sure that no unclean internal st

Indeed, I get the same error with libgiac now. I am not sure what I have done differently before. Though, if I replace e

I cannot answer your main question, but have a few remarks. First, this works fine with libgiac. Secondly, there is a pr

Yes, this looks like a bug and your explanation of the problem seems correct. It is not possible to recover from a crash
