# plugin:mathjax

## Описание

Позволяет вставлять математические формулы. Формулы отображаются правильно ТОЛЬКО при включённом JavaScript.

This plugin adds MathJax to your wiki pages to let you easily write mathematical formulas that will be typeset and displayed cleanly. It is written to be as simple as possible; it loads and configures the script, and no more.

## Изучение

Для изучения синтаксиса, рекомендуется: LaTeX , особенно полезно LaTeX/Mathematics

## Examples/Usage

NOTE that the default configuration uses \$(dollar signs) to delimit TeX formulas. This may cause trouble if you have \$ characters in any pages. The default configuration also lets you escape the dollar signs, however, by changing them to '\$'. This should correct any problems you might have. Once the plugin is installed, you can write TeX formulas in your wiki with the following syntax (by default — all delimiters are configurable): ### Inline Math Use dollar signs:$a^2 + b^2 = c^2$$a^2 + b^2 = c^2\$

or escaped parentheses: $1+2+\dots+n=\frac{n(n+1)}{2}$

$1+2+\dots+n=\frac{n(n+1)}{2}$

### Display Math

To display math on its own line, use double dollar signs:

$$\frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x)$$

$$\frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x)$$

or escaped square brackets:

$\sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right]$

$\sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right]$
