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. <math>\alpha</math> 2. <math>\sqrt{2}</math> 3. <math>\sqrt{1-e^2}</math> 4. <math>\frac{2}{4}=0.5</math> 5. <math>\sum_{k=1}^N k^2</math> 6. <math>\int\limits_{1}^{3}\frac{e^3/x}{x^2}\, dx</math> 7. <math>\begin{bmatrix}
0 & \cdots & 0 \\
\vdots & \ddots & \vdots \\
0 & \cdots & 0
\end{bmatrix}</math> 8. <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.
