This page describes how to use Drupal's TeX implementation, DruTeX.
Rendering LaTeX / Math
Writing maths works as in LaTeX. Use dollar signs to enclose inline math, e.g. $x^2$. Examples for paragraph math are \[ x^2 \] and $$x^2$$ (both variants are equivalent). There is also a display-style inline math environment, compare $\sum_{k=1}^\infty \frac{1}{k}$ and $!\sum_{k=1}^\infty \frac{1}{k}$.
To make a dollar sign, you have to type \$ as in LaTeX!
Arbitrary LaTeX code can be rendered as in this example: <tex>Let $x^2$ be a natural number.</tex>
There are also more elaborate environments to write math - they support auto-numbering, referencing and more. These environments are <equation> and <equations>. They both support the same attributes.
E.g. rendering an equation with a different resolution: <equation dpi="200">e^{i \cdot \pi} = -1.</equation>
To give the equation automatically a number, you have to give it an id: <equation id="euler">e^{i \cdot \pi} = -1.</equation>
You now can produce a link to that equation by typing \ref{euler}, or even better (\ref{euler}).
You can also give it a name instead of a number: <equation id="euler" name="Euler's Identity">e^{i \cdot \pi} = -1.</equation>
An example for the <equations> environment is given by:
<equations>
\int \ln(x) \;dx
&= \int 1 \cdot \ln(x) \;dx \\
&= x \cdot \ln(x) - \int x \cdot \frac{1}{x} \;dx \\
&= x \cdot \ln(x) - x
</equations>
The spaces on the left are optional.
PDF Generator
The pdf version of a node can be retrieved by accessing drutex/pdf/nid where nid is the node id. But only users with the "access pdf files" flag can access this link! You can configure this on the access controal page admin/access. There is also the possibility to get the LaTeX source by accessing drutex/tex/nid.
Verbatim
To prohibit some text from being processed by DruTeX, you can use <code> and <notex>, e.g. <notex>$x^2$</notex>.
