Why do you consider it better to write
 * $$ \sum_{k=1}^{\it INF} $$

than the following?
 * $$ \sum_{k=1}^\infty $$

You also introduced a lot of unnecessary complications in TeX code that make editing harder, like \left( q \left( m \right) \right), where you could have written q(m), or {\frac{ab}{cd}} where \frac{ab}{cd} would suffice. Michael Hardy (talk) 02:57, 14 March 2015 (UTC)


 * The LateX code was generated by Maple software automatically,it is probably isthe standard tex code anyway, some of the tex codes are rather complicated and fills up half a page, so I don't want to mess with it, as the Maple code always printed out correctly. I few times I tried to "edit" it, and end up with the  "unable to parse" etc etc  and then I have to  enlarged the teX 200%, and check it symbol by symbol and try to "debug", it is a nightmare.-唐戈 (talk) 23:32, 15 March 2015 (UTC).


 * The difference is subtle:

$$f \left( x \right) =\sum _{k=1}^{\frac {1}{\sqrt {k!}{x}^{k }\cos \left( kx \right) }} $$ is NOT MAPLE  executable

substituted x=0.5, MAPLE's answer is UN-evaluated:

$$f \left( 0.5 \right) =\sum _{k=1}^{\infty }{\frac {1}{\sqrt {k!}{ 0.50000000000000000000}^{k}\cos \left( 0.50000000000000000000\,k \right) }}$$

On the other hand,

$$f \left( x \right) =\sum _{k=1}^{INF }{\frac {1}{\sqrt {k!}{x}^{k} \cos \left( kx \right) }}$$ is MAPLE executable.

Since the series is fast convering, hence set INF=30,or even INF=400, can easily get numerical value

$$f \left( 0.5 \right) = 34.594861767048513102$$INF=40

$$f \left( 0.5 \right) = 34.594861728083420963$$ INF=400

Of course, $$\infty$$ is the right display format, I should reset $$INF=\infty$$for display--唐戈 (talk) 00:14, 16 March 2015 (UTC).

Hello, I'm JohnBlackburne. I noticed that you recently removed some content from Wikipedia:Articles for deletion/Fibonacci hyperbolic functions without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; I restored the removed content. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

Please do not remove Articles for deletion notices from articles or remove other people's comments in Articles for deletion pages, as you did with Bogoyavlenski-Konoplechenko equation. Doing so won't stop the discussion from taking place. You are, however, welcome to comment about the proposed deletion on the appropriate page. Thank you. JohnBlackburne wordsdeeds 12:44, 9 May 2015 (UTC)

ANI notice
There is currently a discussion at Administrators' noticeboard/Incidents regarding an issue with which you may have been involved. Thank you.-- JohnBlackburne wordsdeeds 13:14, 9 May 2015 (UTC)

Removing AfD template
Please stop your disruptive editing. If you continue to remove Articles for deletion notices or comments from articles and Articles for deletion pages, as you did at Fibonacci hyperbolic functions, you may be blocked from editing. This is an automated message from a bot about, where you removed the deletion template from an article before the deletion discussion was complete. If this message is in error, please report it.—cyberbot I  Talk to my owner :Online 13:54, 9 May 2015 (UTC)
 * Likewise, do not remove standardized templates from within the AfD discussion at Articles for deletion/Fibonacci hyperbolic functions, such as . --- Barek (talk • contribs) - 16:11, 9 May 2015 (UTC)

 * So, it's all our fault? You used the account that you are blaming the system for making. Here's an example of you using the accounts in an illegitimate manner. You created the article with one account and edit warred with the other. There are other examples of you using accounts illegitimately. You tried blanking this AfD and this one with this undeclared account. It makes your response here, "...you are bloody ignorant..." rather ironic.


 * What's this? "I do not permit my plots to appear on en.wikipedia" and so you delete from the English Wikipedia whereas, it is okay for other wikis? That doesn't work. Somebody decided to throw their toys out of the pram here with all those removals on May 16-17 2015 with their main account. Once you have made your contributions then they are licensed for use here, yes? You can't decide to disallow your images or contribs from being used on the English Wikipedia but that they may be used on the ones of your choice...it doesn't work that way.

 * I'm not the one guilty of abuse.

1) Subminiature Photography 2)  Chinese Mathematics
 * I am an expert in  two  areas

Since |I am blocked from editing English wikipedia , the Chinese Mathematics article in  wikipedia still stay  in  2017 ,no body add any  newer content, pity Similarly, the content Minox in wikipedia also  stay  at  2017 no body able to add any new content pity.

I draw up a  nicer picture of sensitometric H D curve for Photographic film and post it  to  Chinese wikipedia This picture is not available to en wikipedia. It is a loss to English readers. Block me ?? You actually block all English readers HD曲線

expertise to provide a similar mathematical expression  describing exactly the  HD curve I am  at least five years ahead  of you  guys. I am the pioneer.You guys are the lagards.
 * I bet  non of you has the

Lagards blocking pioneer,it is quite ridiculous
