# What are some quick ways to turn an article into presentation slides?

My article is like

\documentclass[10pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\begin{document}

\section*{...}
...

\section*{...}
...

\end{document}


I wonder what are some quick ways to turn it into slides?

Or is it viewable if projecting the article directly on a screen hanging from a wall in a classroom using general equipments?

You can of course just project the article, but usually the problem is that an article has far too much text to make a good slide presentation so the slides need to be a summary of the highlights, which tends to be a human review process rather than a mechanical one. –  David Carlisle Sep 25 '12 at 14:54
Recompile using the class slides with the option landscape. This will increase the font size so that it is nicely viewable with projection equipment. However, a 1 page article will become 8-20 slides. Even though this is a kludge, I do this in the classroom when I want to quickly show in class a proof or homework solution with having to build a beamer class presentation. –  R.

@R.Schumacher: Thanks! In your last sentence, do you mean without having to build a beamer class presentation? –  Tim Sep 25 '12 at 15:24
@Tim: Yes, without an build of a beamer. Take any current article class document you have built and just change the class to slides and see the result. –  R. Schumacher Sep 25 '12 at 15:38
@R.Schumacher: For slides, there is no section environment. What do you recommend to replace it and used as some subtitles? Or is there some common environment that can be shared between slidesand article? –  Tim Sep 25 '12 at 15:46

This is the duplicate answer I gave to Math slides looking like notes

Here is example code using slides

\documentclass[landscape]{slides}
\usepackage{amssymb,amsmath,amsthm}
\pagestyle{empty}

\begin{document}
$y'''+4y''+3y'=x^2\cos x-3x$
First, we solve for $y_c$. The auxiliary equation is
\begin{eqnarray*}
m^3+4m^2+3m&=&m(m^2+4m+3)\\
&=&m(m+3)(m+1)\\
m&=&0, -3, -1
\end{eqnarray*}
Hence $y_c=c_1+c_2e^{-3}x+c_3e^{-1}$.\par
For the left side, the annihilator will be
$$(D^3+4D^2+3D)y$$ $$=D(D^2+4D+3)y$$
$$=D(D+3)(D+1)y$$
\end{document}


Note: You will often have to manually break the equations to keep them on the slide.

This is full of "no-no" things in LaTeX; slides is an obsolete class; $$ should not be used in LaTeX; eqnarray neither. – egreg Sep 25 '12 at 15:58 Thanks! I realized two problems. (1) For slides, there is no section environment. What do you recommend to replace it and used as some subtitles? Or is there some common environment that can be shared between slidesand article? (2) An equation within $$ ...  that is too long for a single line cannot be automatically continue at the next line but disappear at the right end, even without landscape. (3) With landscape, a long line of text cannot automatically continue at the next line. –  Tim Sep 25 '12 at 16:02
