Found problem. The mathjax works great if all equations are properly input!
However in sage editor, if you have an open <span> tag and you edit before the end </span> tag, it will sometimes do a "dreamweaver" thing of closing the <span>tag and reopening it. You cannot see this in the editor. This may happen even if you are inside jsmath / mathjax delimiters. So then you get <span> tags INSIDE your equation. In jsmath, this still renders properly, in mathjax it does not. Recommendation: Do not edit equations in editor. ALWAYS edit in html mode. (I have had similar problem in wikispaces too.) -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
