I'm mathematician and professor, and Maxima is a great CAS to work at classes. I and my students of Engineering, work with it. Actually I recomend it to collegues and students of Sciencies and Engineerings. Maxima is extremly easy to use. Before, I used to use Maple, but now I'm a Maxima user.
Very interesting project I liked thanks!
Wm maxima is the best. I think we can do every think with this like: xn--mgbadfb4bp3lqaoh.xn--mgba3ae5h.net
Probably the best free CAS. Is a maxima-sbcl-5.39.x-win64.exe coming soon? Apparently it isn't. Seems all we get for Windows now is various dumb installers created by people who don't know how Windows works and think it's fine to make you install the program somewhere other than in "Program Files" :-(
