Math slides looking like notes

I have seen some slides that look close to notes. For example,this one. I wonder what templates they are created? Not seem like by beamer, as there are more contents in each slide and not fancy at all.

beamer is the right tool. – Harish Kumar Sep 25 '12 at 14:01
"there are more contents in each slide and not fancy at all" compare to beamer. – Tim Sep 25 '12 at 14:02
This looks a use of the slides class – Andrew Swann Sep 25 '12 at 14:14
Possible with beamer with its plain frames. – Harish Kumar Sep 25 '12 at 14:24
The linked document was indeed produced with the slides class, as shown by the source code: icmslides6.tex – diabonas Sep 25 '12 at 16:01

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.

For some reason or the other, I don't get the landscape to work on my compilation??? Weird. – azetina Sep 25 '12 at 15:55
