[sage-devel] sage-2.8 on sunday

2007-08-11 Thread William Stein
Hi, I'm going to release sage-2.8 tomorrow (Sunday), so if you have any patches you're about to send me, send them to me asap. I will release something tomorrow one way or another, even if it possibly means not upgrading, e.g., linbox or something. It's really important to get some important bu

2007-08-11 Thread Timothy Clemans
I think SymPy is going to be useful when a good geometry module is released, and hopefully a trigonometry module will also come out. Once that happens it won't take much to meet the needs of all high school math classes since we already have really good symbolic support that includes functions use

[sage-devel] Yacas in Sage?

2007-08-11 Thread znmeb
Has anyone considered adding Yacas to Sage? They just released version 1.1.0, and have an ambitious road map that seems at least philosophically compatible with Sage. See http://yacas.sf.net/ and http://sourceforge.net/mailarchive/forum.php?thread_name=F0A91E14-1B68-435F-93A9-313ECF8400AF%40xs4
