Demonstration of LaTeX features, using example input and output files

This demonstration LaTeX file shows both the marked up input text, and the corresponding typeset output. The typeset output is a series of graphic images and will not display on a text-only browser. Note that the output images shown here are low resolution JPEG files made from capturing screen images. The actual LaTeX output will use the normal resolution of your output device and look much better.

This demonstration file shows how to use LaTeX markup commands to typeset various types of text, including indented lists, tables, and mathematical equations.

The original input manuscript has been broken into small sections. Each section is then followed immediately by the corresponding portion of the typeset output. Horizontal rules separate input and output sections.

You can also download the complete input manuscript and process it with the latex program yourself to produce nicely formatted high resolution output.

This article demonstrates a basic set of LaTeX formatting commands.
Compare the typeset output side-by-side with the input document.

\section {Plain Text}
Type your text in free-format; lines can be as long
or as short
as you wish.
      You can indent      or space out
        your input
          text in
            any way you like to highlight the structure
      of your manuscript and make it easier to edit.
LaTeX fills lines and adjusts spacing between words to produce an
aesthetically pleasing result.

Completely blank lines in the input file break your text into
paragraphs.
To change the font for a single character, word, or set of words,
enclose the word and the font changing command within braces,
{\em like this}.
A font changing command not enclosed in braces, like the change to \bf
bold here, keeps that change in effect until the end of the document or
until countermanded by another font switch, like this change back to
\rm roman.

\section {Displayed Text}
Use the ``quote'' and ``quotation'' environments for typesetting quoted
material or any other text that should be slightly indented and set off
from the normal text.
\begin{quotation}
The quote and quotation environments are similar, but use different
settings for paragraph indentation and spacing.

\em When in doubt, consult the manual.
\end{quotation}

So far, I have demonstrated titles, paragraphs, font changes, and
section headings.
Now, I am going to show lists and tables.

\begin{enumerate}
\item
The ``enumerate'' environment numbers the list elements, like this.

Items in a list can contain multiple paragraphs.
These paragraphs are appropriately spaced and indented according to their
position in the list.
  \begin{itemize}
  \item The ``itemize'' environment sets off list items with ``bullets'',
like this. Finally, the ``description'' environment lets you put your own
    \begin{description}
    \item[A] label on each item, like this ``A''.
    \item[If the label is long,] the first line of the item text will
be spaced over to the right as needed.
    \end{description}

  \item Of course, lists can be nested, each type up to at least four levels.
One type of list can be nested within another type.
    \begin{itemize}
    \item Nested lists of the same type will change style of numbering
or ``bullets'' as needed.
   \end{itemize}
  \end{itemize}
\item Don't forget to close off all list environments with the
appropriate \verb+\end{...}+ command.
Indenting \verb+\begin{...}+, \verb+\item+, and \verb+\end{...}+
commands in the input document according to their nesting level can help
clarify the structure.
\end{enumerate}

Here is a very simple table showing data lined up in columns.
Notice that I include the table in a ``center'' environment to display
it properly.
The title is created simply as another paragraph in the center environment,
rather than as part of the table itself.
\begin{center}
Numbers of Computers on Earth Sciences Network, By Type.

\begin{tabular}{lr}
Macintosh&175\\
DOS/Windows PC&60\\
Unix Workstation or server&110\\
\end{tabular}
\end{center}

Here is a more complicated table that has been boxed up, with a multi-column
header and paragraph entries set in one of the columns.
\begin{center}
\begin{tabular}{|l|c|p{3.5in}|}
\hline
\multicolumn{3}{|c|}{Places to Go Backpacking}\\ \hline
Name&Driving Time&Notes\\
&(hours)&\\ \hline
Big Basin&1.5&Very nice overnight to Berry Creek Falls from
either Headquarters or ocean side.\\ \hline
Sunol&1&Technicolor green in the spring. Watch out for the cows.\\ \hline
Henry Coe&1.5&Large wilderness nearby suitable for multi-day treks.\\ \hline
\end{tabular}
\end{center}

\section {Mathematical Equations}
Simple equations, like $x^y$ or $x_n = \sqrt{a + b}$ can be typeset right
in the text line by enclosing them in a pair of single dollar sign symbols.
Don't forget that if you want a real dollar sign in your text, like \$2000,
you have to use the \verb+\$+ command.

A more complicated equation should be typeset in {\em displayed math\/} mode,
like this:
\[
z \left( 1 \ +\ \sqrt{\omega_{i+1} + \zeta -\frac{x+1}{\Theta +1} y + 1}
\ \right)
\ \ \ =\ \ \ 1
\]
The ``equation'' environment displays your equations, and automatically
numbers them consecutively within your document, like this:
\begin{equation}
\left[
{\bf X} + {\rm a} \ \geq\
\underline{\hat a} \sum_i^N \lim_{x \rightarrow k} \delta C
\right]
\end{equation}

\end{document}
