*'''Delete''' per Blackburne. Trivial modification of standard hyperbolic functions. There is no useful encyclopedic content. [[User:Sławomir Biały|<span style="text-shadow:grey 0.3em 0.3em 0.1em; class=texhtml">Sławomir Biały</span>]] ([[User talk:Slawekb|talk]]) 16:25, 9 May 2015 (UTC)

*'''Comment'''--It is listed in '''''CRC Concise Encyclopedia of Mathematics''''',you are bloody ignorant

https://books.google.ca/books?id=aFDWuZZslUUC&pg=PA1038&dq=hyperbolic+fibonacci+functions&hl=en&sa=X&ei=mQtOVYWuCo2nyAS3goCoCg&ved=0CCsQ6AEwAw#v=onepage&q=hyperbolic%20fibonacci%20functions&f=false

and Mathworld,

[[Wikipedia:Coverage of Mathworld topics#F]]

Can you explain why content listed in Mathworld should not appear on wikipedia

*'''Commment''' Provide valid reason an article requested by Wikipedia Mising Science topis should be deleted and remain missing ???????????

*'''Comment'''-{{U|唐戈}}-sorry you can't vote more then once. [[User:Wgolf|Wgolf]] ([[User talk:Wgolf|talk]]) 16:43, 9 May 2015 (UTC)

*'''Delete''' per [[WP:TNT]]. Regardless of the possible notability of this topic, the content of the article is a pointless explosion of formulas and plots that adds no value to the encyclopedia. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 20:36, 9 May 2015 (UTC)

::Having looked at one of the sources I can see where these are from. The similarity of [[Binet's formula]] to the [[hyperbolic functions]] means this straightforward transformation turns the latter into the former, and lets you e.g. generate [[Fibonacci numbers]] from them, and so plug them into formulae/properties of those numbers. But that’s the sum total what‘s interesting about them, it could easily be covered by a sentence in one or both of these articles, and none of it appears in this article. So yes, [[WP:TNT]].--<small>[[User:JohnBlackburne|JohnBlackburne]]</small>^{[[User_talk:JohnBlackburne|words]]}<sub style="margin-left:-2.0ex;">[[Special:Contributions/JohnBlackburne|deeds]]</sub> 15:05, 10 May 2015 (UTC)

*'''Comment''' If this is kept, it desperately needs lots of [[TeX]] copy-editing. Stuff like this:

::: <math> \cdots +(2/5)*\sqrt(5)*(5+\sqrt(5))*ln(1/2+ (1/2)*\sqrt(5))^2 * x^2/(\sqrt(5)+1) + \cdots </math>

: that ought to look like this:

::: <math> \cdots +\frac 2 5 \sqrt 5 (5+\sqrt 5)\ln\left(\frac 1 2 + \frac 1 2 \sqrt5\right)^2 \cdot \frac{x^2}{\sqrt{5}+1} + \cdots </math>

: Note <math>\sqrt(5)</math> versus <math>\sqrt 5</math>, <math>ln</math> versus </math>\ln</math> the vulgar asterisk, and other things. [[User:Michael Hardy|Michael Hardy]] ([[User talk:Michael Hardy|talk]]) 04:10, 11 May 2015 (UTC)

::Even after your cleanups that formula needs help. Notice, for instance, that the subexpression

:::<math>\frac 2 5 \sqrt 5 (5+\sqrt 5)</math>

::can be simplified to

:::<math>2+2\sqrt 5.</math>

::To me this sort of problem is illustrative of why we shouldn't just blindly paste computer-program output into Wikipedia without understanding it. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 05:11, 11 May 2015 (UTC)

::Actually there is also a factor of <math>1 + \sqrt{5}</math> in the denominator of that term. So the subexpression

:::<math>\frac 2 5 \sqrt 5 (5+\sqrt 5) \cdot \frac{1}{1 + \sqrt{5}}</math>

::can be simplified to

:::<math>2</math>.

:::Yes, even worse. This is a fine example of [[Mathematics Made Difficult]]. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 20:32, 11 May 2015 (UTC)

*'''Delete''' as essentially [[WP:OR|original research]]. While it is certainly useful and interesting, I don't see an encyclopedia article on the topic. 16:19, 15 May 2015 (UTC)
