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)

Equivalent norms on a vector space (functional anlysis)
Prove that the equivalent norms on a vector space X induce the same topology on X.

Why isn't Israel listed under "Mathematicians" ?
There are some quite prominent mathematicians from Israel.

Reference desk for questions about mathematics?
As I understand it, the questions page is not for questions about mathematics. Wikipedia has a Reference desk for such questions. I don't like the idea of it, but I think, also if we don't introduce it, users will still ask questions where they think is appropriate, even if we recommend a Q&A forum. --barto (talk) 09:29, 6 September 2017 (EDT)

A better name would be a "Request a proof" page. --barto (talk) 09:31, 6 September 2017 (EDT)
