Feel free to add a "brief mention of such second-tier functions" to the [[Hyperbolic function]] page. Adumbrativus mentioned that this redirect target may not be best for [[Tanc function]], this is a small fix for someone better at math. <small>[[Wikipedia:NACD\|(non-admin closure)]]</small> <span style="border-radius:8em;padding:0 7px;background:orange">[[User:I'm tla\|<span style="color:white">'''TLA'''</span>]]</span> [[User talk:I'm tla\|(talk)]] 17:00, 18 January 2024 (UTC) ▲===[[:Coshc function]]=== <noinclude>{{AFD help}}</noinclude> :{{la\|1=Coshc function}} – (<includeonly>[[Wikipedia:Articles for deletion/Coshc function\|View AfD]]</includeonly><noinclude>[[Wikipedia:Articles for deletion/Log/2024 January 12#{{anchorencode:Coshc function}}\|View log]]</noinclude> \| [[Special:Diff/1191699788/cur\|edits since nomination]]) :{{la\|1=Sinhc function}} – (<includeonly>[[Wikipedia:Articles for deletion/Sinhc function\|View AfD]]</includeonly><noinclude>[[Wikipedia:Articles for deletion/Log/2024 January 12#{{anchorencode:Sinhc function}}\|View log]]</noinclude> \| [[Special:Diff/1191699788/cur\|edits since nomination]]) :{{la\|1=Tanhc function}} – (<includeonly>[[Wikipedia:Articles for deletion/Tanhc function\|View AfD]]</includeonly><noinclude>[[Wikipedia:Articles for deletion/Log/2024 January 12#{{anchorencode:Tanhc function}}\|View log]]</noinclude> \| [[Special:Diff/1191699788/cur\|edits since nomination]]) :{{la\|1=Tanc function}} – (<includeonly>[[Wikipedia:Articles for deletion/Tanc function\|View AfD]]</includeonly><noinclude>[[Wikipedia:Articles for deletion/Log/2024 January 12#{{anchorencode:Tanc function}}\|View log]]</noinclude> \| [[Special:Diff/1191699788/cur\|edits since nomination]]) :({{Find sources AFD\|title=Coshc function}}) :({{Find sources AFD\|title=Sinhc function}}) :({{Find sources AFD\|title=Tanhc function}}) :({{Find sources AFD\|title=Tanc function}}) This concept <math>\operatorname{coshc}(x) = \cosh(x) / x</math> is not notable. To begin, I checked the four sources cited in the article. The first, den Outer et al. [https://doi.org/10.1364/JOSAA.10.001209], at one point contains <math>\frac{\cosh \kappa r}{\kappa r}</math> as part of a larger equation, and that's all. The second (Körpinar [https://doi.org/10.1007/s10773-014-2118-5]), third (Sönmez [https://www.m-hikari.com/imf-password2009/37-40-2009/sonmezIMF37-40-2009.pdf]), and fourth (ten Thije Boonkkamp et al. [https://link.springer.com/article/10.1007/s10915-012-9588-5]) contain neither "coshc" nor even <math>\cosh x / x</math> for anything in place of ''x''. The article also formerly cited http://mathworld.wolfram.com/CoshcFunction.html which is currently a dead link and I can't confirm it ever existed. I found no other potential sources from a search.

All suffer from the same lack of independent notability, and all can be included as a brief definition under the [[Hyperbolic function]] page. Pinging {{ping\|David Eppstein}} for an expert opinion. [[User:OwenX\|Owen×]] [[User talk:OwenX\|<big>☎</big>]] 14:13, 13 January 2024 (UTC) :I have added these other three pages as suggested; hopefully I didn't screw up any of the technicalities on the backend. [[User:XOR'easter\|XOR'easter]] ([[User talk:XOR'easter\|talk]]) 20:38, 13 January 2024 (UTC) ::Thanks! No problem - I'm pinging David Eppstein about this - he was the only one who hasn't seen the update yet. [[User:OwenX\|Owen×]] [[User talk:OwenX\|<big>☎</big>]] 20:59, 13 January 2024 (UTC) :Comment from nominator after sinhc, tanhc, and tanc were added: I am happy to support '''redirect''' for [[Sinhc function]], [[Tanhc function]], [[Tanc function]], but I think targeting [[Sinc function]] is more natural. I guess it would be a brief mention in the history/etymology context, as names sometimes used by analogy. Certainly [[Hyperbolic function]] isn't a proper target for [[Tanc function]]. I originally proposed to delete [[Coshc function]] rather than redirect because that name is at best very obscure or at worst completely made up (more so than the others), but I don't object to a redirect to sinc if the other ones get redirected there too. [[User:Adumbrativus\|Adumbrativus]] ([[User talk:Adumbrativus\|talk]]) 05:33, 17 January 2024 (UTC) '''Redirect'''. We have chosen to group our trigonometric and hyperbolic functions into bundles; for instance, we do not even have a separate article for cosine. Given that, we should not make an exception for this one function. —[[User:David Eppstein\|David Eppstein]] ([[User talk:David Eppstein\|talk]]) 17:22, 13 January 2024 (UTC) :{{ping\|David Eppstein}} while I can guess your answer, for the sake of pro-forma, can you confirm your !vote also applies to the three other functions added to the AfD since your comment? Thanks!

The "literature" on the topic is paltry ''and admits as much'': {{tq\|The hyperbolic function <math>\sinh(x)/x</math> receives scant attention in the literature.

I wonder if any of the sources referenced on the [[Circular definition]] page reference the Wikipedia article in turn. [[User:OwenX\|Owen×]] [[User talk:OwenX\|<big>☎</big>]] 18:22, 13 January 2024 (UTC) :Regarding the MathWorld business, I've been [[User:XOR'easter/So,_you've_decided_to_write_about_physics_and/or_mathematics_on_Wikipedia#Websites,_social_media,_and_discussion_groups\|keeping a list]] of examples where that site has been a shoddy source, particularly for names. I don't think they have very high standards; sometimes it seems that if one person said it one time, MathWorld will accept it as a term. [[User:XOR'easter\|XOR'easter]] ([[User talk:XOR'easter\|talk]]) 20:45, 13 January 2024 (UTC) *'''Redirect all'''.
