Writing LaTeX

There are many excellent introductions to writing mathematics with LaTeX, for example Introduction to LaTeX. Below is a quick and dirty example to start with.

LaTeX is the language in which most mathematics and physics documents are written. Mathematical symbols and equations are written in a special markup. For example an integral sign is inserted with \int. The best way to learn LaTeX is by example. Here is a basic LaTeX file:

\documentclass[a4paper,10pt]{article} \usepackage{amsfonts,amsthm,amsmath,amssymb} \title{Simple example}

\begin{document} \maketitle

\section{Quadratic equation}

We want to solve \(ax^2+bx+c\). The solution is \begin{equation} x= \frac{-b\pm \sqrt{b^2 -4ac}}{2a} \end{equation}

\end{document}

LaTeX commands start with a back slash \. Sometimes they have an argument in curly brackets, e.g \sqrt{b^2-4ac}. Most of the commands in the document above are self-explanatory.

To convert this into a readable document first save it into a file with a .tex extension, e.g. sample.tex. Then you need to process it. If you are using GNU/Linux, see Processing LaTeX with GNU/Linux systems.
