How to use equation numbers?
Does anyone have a good example?


 * Manually. There is no automatic way of linking within a page except through headlines which isn't appropriate for equation numbering. I do it something like this:
 * $(1) \qquad x = y$
 * blah blah yadayada
 * ... and so from equation $(1)$ we have: ...


 * It's as good a way as any other. --prime mover 05:20, 20 October 2010 (UTC)


 * Incidentally, as I fixed up the math tags from this now, I remembered that the eqn template now has an explicit way to do this


 * I feel like there was maybe a neat way to back-reference, or that could just be wishful thinking. If anyone, remembers... --Alec  (talk) 00:23, 25 June 2011 (CDT)


 * There is a way of internal referencing, but it's tied up with display equations (see the sandbox, I believe) and that doesn't suit our house style. If there were a way of fixing display equation style so as to put it one tabsworth indented on the left rather than centred, we would be able to use it. But probably not in the equation template, unfortunately.
 * Another incidentally, so as to improve look&feel and to make it consistent with the other equation numbering style, I'm about to stick a colon into the n line into the eqn template.--prime mover 02:02, 25 June 2011 (CDT)
