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.

 * Please note, however, that is a compendium of proofs, not an online math help service.


 * In this particular case, Lipschitz Equivalent Metrics are Topologically Equivalent seems to be very close to what you're looking for. &mdash; Lord_Farin (talk) 16:49, 22 March 2014 (UTC)

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)


 * Personally I don't think that we should encourage ad hoc requests for proofs. This is contrary to the systematic approach that we envisage, and (as I have seen on maths.SE) increases mostly the amount of relatively easy questions. In the end, we don't strive to support this kind of Q&A style, so I don't think we should invest much energy in something that encourages it.
 * Maybe I'll reconsider if the influx of questions gets very big &mdash; but currently we should be fine with this approach. &mdash; Lord_Farin (talk) 12:16, 6 September 2017 (EDT)


 * Just to make sure my opinion on this is clear, I agree with Lord_Farin.
 * What I do think we can add, is a page with instructions what to do instead. So not Help:Request a Proof, but rather something like Help:Report Missing Content --barto (talk) 14:54, 6 September 2017 (EDT)

Sources in other languages
I've done some work on the affine space definition; my only source is a geometry text book written in French I kept hold of. It doesn't really seems appropriate for an english language wiki to add this as a reference? --Linus44 (talk) 14:38, 26 February 2019 (EST)


 * I see no reason why not. There are other foreign language sources there that have been used. I'm planning on plundering Le Lionnais when I get to it. The only restriction is the actual work itself that fills the pages is in English.


 * Good to have you back, by the way. --prime mover (talk) 15:18, 26 February 2019 (EST)


 * I suppose it's also nice to cite the author's original work for a named theorem, in which case it couldn't be avoided be avoided. --Linus44 (talk) 16:21, 26 February 2019 (EST)
