Questions answered by this recipe

How do I easily display formulas in LaTeX-style with PmWiki?

All sections are optional, you can remove those that do not apply to your recipe, and add new ones.

Description

If you know how to typeset formulas with LaTeX, you can typeset formulas with PmWiki in the very same style.

In LaTeX formulas are typeset using the $-sign as formula delimiter. A centered formula on its own line is typeset with the double $-sign, For example, the following formula markup

$$ \sum_{i=1}^{n}i = \frac{n(n+1)}{2} $$

displays as:

Installation

Latest MathJax version: LaTeXMathJax.phpΔ

Note: Requires MathJax 2.x and does not work with current (3.x+). You will want to download a 2.x version of MathJax and place in your site pub/MathJax folder.

Just copy the above script to your cookbook/ and add include_once("cookbook/LaTeXMathJax.php"); to your local/config.php .

Usage

Example for in-line formula style:

The quadratic polynomial $f(t) = c_0 + c_1t + c_2t^2$ has three coefficients $c_0, c_1, c_2$.

Example for centered formula style:

$$ \left( \begin{array}{c c c} n & \sum_i t_i & \sum_i t_i^2 \\ \sum_i t_i & \sum_i t_i^2 & \sum_i t_i^3 \\ \sum_i t_i^2 & \sum_i t_i^3 & \sum_i t_i^4 \end{array} \right) \left( \begin{array}{c} c_0 \\ c_1 \\ c_2 \end{array} \right) = \left( \begin{array}{c} \sum_i m_i \\ \sum_i m_i t_i \\ \sum_i m_i t_i^2 \end{array} \right) $$
