\(\LaTeX\) can be included in wiki articles by using <code><nowiki><math>...</math>x_{1</nowiki></code> tags,2} = <code>\<span></span>( ... \frac{-b <span></span>)</code> or <code>\pm <span></span>[ ... \sqrt{b^2 - 4 a c}}{2 a}<span></mathspan>]</code>.
Foo bar $x_i$ baz $y_i = m x = <nowiki><math></nowiki> tags == For instance, the following line... Quadratic equations of the form <nowiki><math>0 = ax^2 + c_i$bx + c</math></nowiki> can be solved by using <nowiki><math>x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a}</math></nowiki>. ...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 == <code>\<span></span>[ ... \<span></span>]</code> 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: \<span></span>[ x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a} \<span></span>]\[ x_{1,2} = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a} \] <code>\<span></span>( ... \<span></span>)</code> can also be used as delimiters for inline maths, for instance:<code>\<span></span>( \nabla B = \nabla \times \vec Q \<span></span>)</code>becomes \( \nabla B = \nabla \times \vec Q \). == Escaping == <nowiki><nowiki></nowiki> tags don't escape the bracket delimiters unfortunately (but do escape <nowiki><math></nowiki> tags). Brackets can be escaped by including a <code><nowiki><span></span></nowiki></code> between the <code>\</code> and the opening/closing bracket, like so: <nowiki>\<span></span>( \nabla B = \nabla \times \vec Q \<span></span>)</nowiki> == Chemical formulas == [https://www.mediawiki.org/wiki/Extension:SimpleMathJax SimpleMathJax] also supports [https://mhchem.github.io/MathJax-mhchem/ <nowiki><chem></nowiki> tags], like so: <nowiki><chem>CO2 + C -> 2 CO</chem></nowiki><chem>CO2 + C -> 2 CO</chem> == Edit previews == Thanks to a hack in [[MediaWiki:Common.js]], maths now show up in edit previews.
