# Talk:Cauchy Mean Value Theorem

Edited the order of the functions in the proof section, in the equation solved for h. g(b) and g(a) were reversed. A minor error, to be sure! - ThomasLantern 19:49, 16 July 2011 (CDT)

Good call. Changed it again to put the functions back the other way but negated the entire fraction, which makes it neater.--prime mover 01:47, 17 July 2011 (CDT)

Added an example. I could not add the source of the example (http://math.stackexchange.com/a/296194/364569) as I'm a beginner at editing articles. --R30 23:23, 17 August 2016 (CDT)

Added a geometrical interpretation. I could not add the source of the example (http://math.stackexchange.com/a/1290321) as I'm a beginner at editing articles. This is the image source: https://en.wikipedia.org/wiki/Mean_value_theorem#/media/File:Cauchy_svg.svg. --R30 22:16, 17 September 2016 (CDT)

Our house rules are such that we do not allow the transclusion of external sources. There are many reasons for this, the most telling one being that the internet is ephemeral, and there is no guarantee that a resource that is included (or even linked to) is going to be there in the future. Therefore all expositionary material on $\mathsf{Pr} \infty \mathsf{fWiki}$ is held completely internally to $\mathsf{Pr} \infty \mathsf{fWiki}$.
There are exceptions: certain well-structured and managed websites can be used as a source of citations -- certain contributors in the past who are enthusiastic about one source or another have clamoured for such sites to be used as resources for citations -- but such sites have been known to completely change the structure of their link policy. As maintenance of the links to such resources is a burden, we are very reluctant to encourage such usage.
In particular, the very nature of Stackexchange renders it unacceptable for direct linking of resources. Hence your approach in which you transcribed the content of the resources directly into $\mathsf{Pr} \infty \mathsf{fWiki}$ was 100% the correct one.
Clarification of this can be found in the page Help:Sources, although it occurs to me we may benefit from including this point in our FAQ page. --prime mover (talk) 03:48, 18 September 2016 (EDT)
That's good to hear. I think those are great policies, thanks for the detailed explanation! --R30 13:10, 18 September 2016 (CDT)

To add to that, we now have Template:MathSE, which can be used to provide attribution to maths.SE sources where applicable. — Lord_Farin (talk) 12:56, 18 September 2016 (EDT)

Update: not remembering that, I have just created {{Stackexchange}}. We need to merge them. I'll leave that up to anyone who wants to. --prime mover (talk) 20:08, 26 January 2019 (EST)
