We give a brief introduction to the use of \LaTeX\ in the context of REVTeX~4.1.

\section{Introduction}
\LaTeX\ looks more difficult than it is. It is
almost as easy as $\pi$. See how easy it is to make special
symbols such as $\alpha$,
$\beta$, $\gamma$,
$\delta$, $\sin x$, $\hbar$, $\lambda$, $\ldots$\ . We also can make
subscripts,
$A_{x}$, $A_{xy}$, and superscripts, $e^x$, $e^{x^2}$, and
$e^{a^b}$. We will use \LaTeX, which is based on \TeX\ and has
many higher-level commands (macros) for formatting, making

We just made a new paragraph. Extra lines and spaces make no
difference. Note that all formulas are enclosed by
\beta, \gamma, \Gamma,
\delta,\Delta,
\epsilon, \zeta, \eta, \theta, \Theta, \kappa,
\lambda, \Lambda, \mu, \nu,
\xi, \Xi,
\pi, \Pi,
\rho,
\sigma,
\tau,
\phi, \Phi,
\chi,
\psi, \Psi,
\omega, \Omega\$

\subsection{Special symbols}

The derivative is defined as
$$\frac{dy}{dx} = \lim_{\Delta x \to 0} \frac{\Delta y} {\Delta x}$$
$$f(x) \to y \quad \mbox{as} \quad x \to x_{0}$$
$$f(x) \mathop {\longrightarrow} \limits_{x \to x_0} y$$

\noindent Order of magnitude:
$$\log_{10}f \simeq n$$
$$f(x)\sim 10^{n}$$
Approximate equality:
$$f(x)\simeq g(x)$$
\LaTeX\ is simple if we keep everything in proportion:
$$f(x) \propto x^3.$$

Finally we can skip some space by using commands such as
\begin{verbatim}
\bigskip    \medskip    \smallskip    \vspace{1pc}
\end{verbatim}
The space can be negative.

\section{Use of Color}

\section{\label{morefig}Subfigures}

As soon as many users start becoming comfortable using \LaTeX, they want
to use some of its advanced features. So we will show you how to place two
figures side by side.

\begin{figure}[h!]
\centering
\subfigure[\ Real and imaginary.]{
\includegraphics[scale=0.5]{reim}}
\subfigure[\ Amplitude and phase.]{
\includegraphics[scale=0.5]{phase}}
\caption{\label{fig:qm/complexfunctions} Two representations of complex
wave functions.}
\end{figure}

We first have to include the package,
\verb+\usepackage{subfigure}+, which has to go in the preamble (before
\verb+\begin{document}+). It sometimes can be difficult to place a figure in
the desired place.

Your LaTeX document can be easily modified to make a poster or a screen
presentation similar to (and better than) PowerPoint. Conversion to HTML is
straightforward.
