# LaTeX sample

The file below is a simple example explaining how many of the basic LaTeX things work. If you want to play with it on your own computer, you can download it as a LaTeX source file latex_sample.tex (also download the lion.png image). If all is installed correctly, you should be able to produce the latex_sample.pdf file from it.

\documentclass[11pt]{report} % To set margin width, text height, space for footnotes and all sorts % of other settings related to the geometry of the pages in your % report, use the 'geometry' package. % % http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=geometry \usepackage[margin=2cm]{geometry} % For inclusion of figures, use the 'graphicx' package. This allows % you to later include a figure using '\includegraphics{filename}' and % it will also for simple sizing of the figure in your text. % % http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=graphicx \usepackage{graphicx} % You may want to add hyperlinks to your document, which can be tricky % to typeset because they often have weird symbols in them which LaTeX % interprets in its own way. Use 'hyperref' for this. It also has many % options to add e.g. a list of thumbnails to your pdf file. % % http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=hyperref \usepackage[colorlinks=true]{hyperref} % Finally, for various useful tools for mathematics typesetting, use % the 'amsmath' package with a few assorted companion packages which % provide extra symbols. % % http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=amsmath % http://tug.ctan.org/cgi-bin/ctanPackageInformation.py?id=amssymb \usepackage{amsmath} \usepackage{amssymb} % For figure/table caption settings. %\usepackage{varwidth} %\usepackage[noonelinecaption=true]{caption} \begin{document} % The 'article' document class provides a simple way to make a title % page: \title{A report} \author{Someone} \maketitle % A table of contents can be generated automatically as well: \tableofcontents % Now comes the true content. \chapter{A chapter on something} \label{c:intro} \section{A section} \subsection{A sub-section} Some text here. You can \emph{emphasise it} or {\bfseries make it bold-face} or {\large larger} or \emph{\bfseries\large combine those settings}. A random equation: \begin{equation} \label{e:Einstein1} E=mc^2 \,. \end{equation} If you want to align equations, use either {\tt align} or {\tt aligned}. See the examples below. The difference is the way in which the equation numbers are added. Here is the option with the two equations receiving only one number: \begin{equation} \label{e:Einstein2} \begin{aligned} E &= mc^2 \\ i\hbar \frac{\partial}{\partial t} |\psi, t\rangle &= \hat{H} |\psi,t\rangle\,, \end{aligned} \end{equation} and here is the one where every equation gets its own number: \begin{align} \label{e:Einstein3} E &= mc^2 \\ \label{e:Schroedinger} i\hbar \frac{\partial}{\partial t} |\psi, t\rangle &= \hat{H} |\psi,t\rangle\,, \end{align} \chapter{Another chapter} \section{Again a section} You can cite any paper or book which is in your bibliography list (see below). Papers everyone should read are~\cite{Einstein:1935rr} and \cite{Feynman:1948ur}. You can refer to equations, such as~\eqref{e:Einstein3}, or to chapters, such as~\ref{c:intro}, or figures, such as figure~\ref{f:lion}. \begin{figure}[h] \begin{center} \includegraphics[width=.3\textwidth]{lion.png} \end{center} \caption{This is the lion which is the \TeX{} mascotte.\label{f:lion}} \end{figure} And here is a link to a web page: \url{http://www.google.com}. % Finally the bibliography. You can cut and paste these entries % straight from e.g. the inSpire database at http://inspirehep.net

% (select one of the 'LaTeX' output options) or many other maths

% databases. % % A better but more complicated way to do references is to use BiBTeX. \begin{thebibliography}{50} \bibitem{Einstein:1935rr} A.~Einstein, B.~Podolsky and N.~Rosen, ``Can quantum mechanical description of physical reality be considered complete?,'' Phys.\ Rev.\ {\bf 47} (1935) 777. %%CITATION = PHRVA,47,777;%% %\cite{Feynman:1948ur} \bibitem{Feynman:1948ur} R.~P.~Feynman, ``Space-time approach to nonrelativistic quantum mechanics,'' Rev.\ Mod.\ Phys.\ {\bf 20} (1948) 367. %%CITATION = RMPHA,20,367;%% \end{thebibliography} \end{document}
