If you store the
latex_sample.tex file
(also displayed below) and the
lion.png image
file in a directory and run
pdflatex latex_sample.tex
you will get a
latex_sample.pdf output
file which you can view or print.

% 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 the SPIRES database (select one of the 'LaTeX' output
% options).
%
% A better but more complicated way to do references is to use BiBTeX.
