I sort of figured out what dms did (except for the 'select all' button)

There is a very workable LateX converter at http://www.codecogs.com/latex/eqneditor.php

It converts your equations into .gif files which you can then upload on the website.

like what I did here.

I'm hoping that Andrew Massow might be willing to add the editor to the website, because then everyone will be able to use the [tex] [/tex] command

Hi Reinout,
I don't see how this is better than what I already do. I uploaded this latex output just today. Maybe it would be better for really long outputs.

What Dms did was different because I dont think that he actually uploaded anything.
It would certainly be good if Andre was willing to add the editor. I agree.

If he thinks of adding a latex editor, I think the best choice is mathjax.
That is what the other forums are using and a number of those forums have switched to mathjax in the last couple of years.

Hello guys, I'm glad you liked the specific use of Latex.
From what I can see, in this forum the potential for use BBcode tags are few. So should be limited to tags such as [ img], [ code] etc. However it is possible to quote images of equations in the form of LaTex, using this online tool: http://www.codecogs.com/latex/eqneditor.php .
This tool therefore can produce the equation as image with this page: http://latex.codecogs.com/gif.latex? [LaTex HERE]
For example: The equation 2x=5=>x=5/2 as LaTex, is:
2x=5\Rightarrow x=\frac{5}{2}
...so we can export a picture with the equation, using the equation as a parameter to the page http://latex.codecogs.com/gif.latex?2x=5\Rightarrow x=\frac{5}{2}
BUT, now there is a problem: LaTex form is not BBcode-tags-friendly so if you try to put img tag you get:

0

So? How can we solve this problem? The solution is simple:
You have just to encode the equation's LaTex with Base64. Easy to do with this tool: http://meyerweb.com/eric/tools/dencoder/
So you keep the " http://latex.codecogs.com/gif.latex?" and you encode the " 2x=5\Rightarrow x=\frac{5}{2}" and the result:
http://latex.codecogs.com/gif.latex?2x%3D5%5CRightarrow%20x%3D%5Cfrac%7B5%7D%7B2%7D
It is now possible quote the image in the following format:
[img]http://latex.codecogs.com/gif.latex?2x%3D5%5CRightarrow%20x%3D%5Cfrac%7B5%7D%7B2%7D[/img]
And Finally: 0

I hope the above clear up the way in which we can list images easily. If yes,(challenge:) try to post this Quadratic equation as image with Blue numbers: x=(-b+sqrt(b^2-4ac))/2a

The above method can be automated in this forum platform adding some extra plugins. Anyway, if you need some other help that is relevant to the technical part I can help you, yes I'm a programmer, but I am interested in maths!

Have a nice day,
Dms

I am sorry Dms, I am not understanding.
what difference does it make if you posted it on this site? http://imgur.com/
It appears to me that we have to pay to use this software.
Is this not correct?
Thank you
Melody.

When using direct the page http://latex.codecogs.com/gif.latex?, the page have to render the image everytime someone open this thread. This resulting the need of processing resources. From the other side, if you downloaded the image and then you upload it on http://imgur.com/ everything is okay. So the process is now preferred:
[list]
  • Use http://www.codecogs.com/latex/eqneditor.php to make your equation.[/*:m]
  • Download the image[/*:m]
  • Upload on http://imgur.com/[/*:m]
  • Quote here.[/*:m][/list:u]

    Nice, I appreciate it!
    Also, the admin could install a mod on this forum like http://www.mayer.dial.pipex.com/tex.htm. So we can quote very easy mathematical equations.

    Proposed letter to Andre Massow.
    I'll probably send this tomorrow afternoon.
    i have posted it here so that you can comment if you wish to.

    Hello Andre,

    Within the forum we have been discussing the possibility of getting LaTex embedded into the site. This would make the site better for everyone. The answers would be better and we would attract more high level people to answer questions.


    It is thought that Mathjax is the best choice. It is thought to be the recent favourite of other forums. This is what one member, 'I like Serena' had to say concerning it.

    “Mathjax (see https://en.wikipedia.org/wiki/MathJax) is open source software that uses the Apache license:

    The Apache License (/əˈpætʃi/) is a free software license written by the Apache Software Foundation (ASF). The Apache License requires preservation of the copyright notice and disclaimer. Like other free software licenses, the license allows the user of the software the freedom to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software, under the terms of the license, without concern for royalties.

    If it is installed in the web site, we could type latex with [tex][/tex] tags around it. Possibly with alternative tags like dollars.”


    Another member 'Dms' also added.
    “Could admin also install a mod on this forum like http://www.mayer.dial.pipex.com/tex.htm. So we can quote mathematical equations easily.”


    Unfortunately I do not have any personal knowledge of what is best but could you please
    install this/these for us? It would be greatly appreciated.


    Yours Sincerely,
    Melody …

    I just noticed about Mathjax, seems ideal. I hope that Andre can do something about it. Very good job, Melody!

    Hi Dms,
    Do we just need Mathjax or do we need the one you spoke of as well?
    Thanks,
    Melody.

    The truth is that the two mods are equally good! I think we should let the administrator to select which one is better to install for this forum.
