MediaWiki User Guide/Mathematics

You can enter mathematical formulas into a wiki, using a math tag, such as:

<math>\sqrt{2}</math>

The formulas are marked up in the TeX markup, the markup of a complex typesetting system specialized on mathematics.

Before you start writing formulas in this markup, you can consider writing the simpler ones in HTML and wiki markup, such as:

f(x) = b + c / d

which is marked up as

 ''f''(x) = ''b'' + ''c'' / ''d''

Examples

To get started, follow the examples below.

Examples of mathematical markup
No.	Desired Effect	Markup
1.	$\alpha\,\!$	`<math>\alpha\,\!</math>`
2.	$\sqrt{2}$	`<math>\sqrt{2}</math>`
3.	$\sqrt{1-e^2}$	`<math>\sqrt{1-e^2}</math>`
4.	$\frac{2}{4}=0.5$	`<math>\frac{2}{4}=0.5</math>`
5.	$\sum_{k=1}^N k^2$	`<math>\sum_{k=1}^N k^2</math>`
6.	$\int\limits_{1}^{3}\frac{e^3/x}{x^2}\, dx$	`<math>\int\limits_{1}^{3}\frac{e^3/x}{x^2}\, dx</math>`
7.	$\begin{bmatrix} 0 & \cdots & 0 \\ \vdots & \ddots & \vdots \\ 0 & \cdots & 0 \end{bmatrix}$	<math>\begin{bmatrix} 0 & \cdots & 0 \\ \vdots & \ddots & \vdots \\ 0 & \cdots & 0 \end{bmatrix}</math>
8.	$\begin{pmatrix} x & y \\ z & v \end{pmatrix}$	<math>\begin{pmatrix} x & y \\ z & v \end{pmatrix}</math>

Greek and symbols

There is a way of marking up Greek characters and special symbols, as the following table shows.
