[sage-devel] How to know what version of Maxima is sagemath using?

I am on CachyOS Linux. I do not build anything from source anymore and just use pacman package manager to install all software. I installed sagemath using pacman a week ago and also installed maxima 5.47. Everything was working OK. maxima was working oK on its own also. Last night, I did system

I am on arch based system. Installed sagemath using pacman. I no longer build from source. Also installed giac latest using pacman. (same for Fricas and maxima) But when from inside sagemath I do integrate(sin(x),x,algorithm="giac") it returns back the input. Not sure why. >which sage /us

I am on arch linux, and I found that arch pacman package manager has latest sagemath. So I do not have to build sagemath from source, which is much easier. So I used pacman to install sagemath 10.5 , also used it to install giac. The issue is that, I do not know if sagemath is using its own bui

Sometimes when calling integrate using algorithm such as maxima, it returns result which is not fully resolved but still have an integrate inside it. Next, when calling latex() on the anti-derivative this cause problems, because sage tried to calls maxima again on the integrate command inside t

[sage-devel] What is the status of sympy in sagemath? In particular the integrator.
