\(\LaTeX\) can be included in wiki articles by using <math>...</math> tags, \( ... \) or \[ ... \].
Contents
<math> tags
For instance, the following line...
Quadratic equations of the form <math>0 = ax^2 + bx + c</math> can be solved by using <math>x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a}</math>.
...results in:
- Quadratic equations of the form [math]0 = ax^2 + bx + c[/math] can be solved by using [math]x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a}[/math].
Brackets and display formulas
\[ ... \] results in a "display" formula instead of an "inline" one. This is best if the equation is meant to stand on its own, without surrounding flow text:
\[ x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a} \]
\[ x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a} \]
\( ... \) can also be used as delimiters for inline maths, for instance:
\( \nabla B = \nabla \times \vec Q \)
becomes \( \nabla B = \nabla \times \vec Q \).
Escaping
<nowiki> tags don't escape the bracket delimiters unfortunately (but do escape <math> tags).
Brackets can be escaped by including a <span></span> between the \ and the opening/closing bracket, like so:
\<span></span>( \nabla B = \nabla \times \vec Q \<span></span>)
Chemical formulas
SimpleMathJax also supports <chem> tags, like so:
<chem>CO2 + C -> 2 CO</chem>
[math]\ce{CO2 + C -> 2 CO}[/math]
Edit previews
Thanks to a hack in MediaWiki:Common.js, maths now show up in edit previews. At least sometimes.
