− | We use the [http://www.mediawiki.org/wiki/Extension:MathJax MathJax Extension] by [http://www.mediawiki.org/wiki/User:Dirk_Nuyens Dirk Nuyens]. This extension enables [http://www.mathjax.org/ MathJax] (http://www.mathjax.org/) which is a Javascript library written by Davide Cervone. |

− | == Usage == |
||
− | |||
− | The following math environments are defined for inline style math: |
||
− | * <code>\(...\)</code> and |
||
− | * <code><math>...</math></code>. |
||
− | And the following math environments are defined for display style math: |
||
− | * <code><nowiki>$$...$$</nowiki></code> (can be turned off, even per page), |
||
− | * <code>\[...\]</code>, |
||
− | * <code>\begin{...}...\end{...}</code> and |
||
− | * <code>:<math>...</math></code>. |
||
− | MathJax produces nice and scalable mathematics, see their website (http://www.mathjax.org/) for a demonstration. This extension also enables the usage of <code>\label{}</code> and <code>\eqref{}</code> tags with automatic formula numbering. If needed you can still hand label by using <code>\tag{}</code>. |
