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.
