Could someone please rewrite the section on equation arrays to use the align environment rather than the eqnarray environment? I would do it myself, except that I don't have the time right now. --roadnottaken
- No, it's an example on eqnarray. So it must use the eqnarray environment. --1=2 10:42, 12 March 2008 (EDT)
