A Tiny MCE plugin which makes writing latex equation easy and WYSIWYG（what you see is what you get）. It converts latex code into image which shows real beautiful latex equations on your post.
It adds an “fx” botton on the wordpress TinyMCE editor, on clicks it the codecogs latex equation editor pops up, where you can edit latex, then click the copy button to copy the equation image back in TinyMCE textarea.
You can also use this editor to only input latex code and let plugins like quicklatex, mathjax or Latex for WordPess to convert it to equation image, you’d better change line 90 in editor_plugin.js 
tinyMCE.activeEditor.execCommand(‘mceInsertContent’, false, ”); 
to 
tinyMCE.activeEditor.execCommand(‘mceInsertContent’, false, ‘\[‘+latex+’\]’); 
inorder to only copy LaTex code to TinyMCE textarea when click the copy button.
I just followed the tutorial written by Greg Winiarski(http://ditio.net/2010/08/15/adding-custom-buttons-to-wordpress-tinymce/) and make codecogs Tiny MCE plugin(http://www.codecogs.com/latex/integration/tinymce/install.php) into a wordpress plugin. Thanks the great guys. If you can make the plugin better to use please tell me in http://www.verymath.com/2011/05/10/codecogs-latex-equation-editor/
<h3>Arbitrary section</h3>
You may provide arbitrary sections, in the same format as the ones above. This may be of use for extremely complicated 
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or 
“installation.” Arbitrary sections will be shown below the built-in sections outlined above.
<h3>A brief Markdown Example</h3>
Ordered list:
<ol>
<li>Some feature</li>
<li>Another feature</li>
<li>Something else about the plugin</li>
</ol>
Unordered list:
<ul>
<li>something</li>
<li>something else</li>
<li>third thing</li>
</ul>
Here’s a link to <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> and one to <a href="http://daringfireball.net/projects/markdown/syntax" title="Markdown is what the parser uses to process much of the readme file" rel="nofollow ugc">Markdown’s Syntax Documentation</a>. 
Titles are optional, naturally.
Markdown uses email style notation for blockquotes and I’ve been told:
<blockquote>
Asterisks for emphasis. Double it up for strong.
</blockquote>
<pre><code><?php code(); // goes in backticks ?>
</code></pre>

MathJax enables enables rendering of embedded LaTeX or MathML in HTML pages. This plugin adds this functionality to WordPress. The MathJax JavaScript is inject on-demand only to those pages which require it. This ensures that MathJax is not loaded for all pages, which will otherwise slow loading down.
The MathJax JavaScript can be delivered from your own server, or you can use the Cloudflare Content Distribution Network (CDN), which is the preferred mechanism as it offers increased speed and stability over hosting the JavaScript and configuring the library yourself.
You may embed latex using a variety of different syntaxes. The shortcode (https://codex.wordpress.org/Shortcode_API) syntax is preferred. So <code>[latex]E=mc^2[/latex]</code> will work out of the box. This also forces loading of MathJax.
Additionally, you can use native MathJax syntax — <code>$$E=mc^2$$</code> or <code>$E=mc^2$</code>. However, if this is the only syntax used, the plugin must be explicitly told to load MathJax for the current page. This can be achieved by adding a <code>[mathjax]</code> shortcode anywhere in the post. For posts with both <code>[latex]</code>x<code>[/latex]</code> and <code>$$x$$</code> syntaxes this is unnecessary.
You can use wp-latex syntax, <code>$latex E=mc^2$</code>. Parameters can be specified as with wp-latex but will be ignored. This means that MathJax-LaTeX should be a drop-in replacement for wp-latex. Because this conflicts with wp-latex, this behaviour is blocked when wp-latex is present, and must be explicitly enabled in the settings.
You can also specify <code>[nomathjax]</code> — this will block mathjax on the current page, regardless of other tags.
MathJax-LaTeX is developed on <a href="https://github.com/phillord/mathjax-latex" rel="nofollow ugc">GitHub</a>.
