I'd like to make a compact formula sheet with 3 page columns in landscape orientation. I prefer the equations to break at boundaries (semi-)automatically. Currently most of my equations are formatted as equation
. I've read on equation splitting, but I still don't know how to combine it with page columns.
Here's something I glued together:
\documentclass{article}
\usepackage{breqn}
\begin{document}
\begin{minipage}{0.45\textwidth}
\begin{dmath}
Q(\lambda,\hat{\lambda}) = -\frac{1}{2} P(O \mid \lambda ) \sum_s \sum_m \sum_t \gamma_m^{(s)} (t) \left( n \log(2 \pi ) + \log \left| C_m^{(s)} \right| + \left( \mathbf{o}_t - \hat{\mu}_m^{(s)} \right) ^T C_m^{(s)-1} \left(\mathbf{o}_t - \hat{\mu}_m^{(s)}\right) \right)
\end{dmath}
\end{minipage}%
\hfill
\begin{minipage}{0.25\textwidth}
\begin{tabular}{|p{\textwidth}}
This is second part \\
$f(x) = 2x + 3y$ This line may go all along the end and wrap afterwards to the next as seen here\\
This is a forced next line by ending the previous line
\end{tabular}
\end{minipage}%
\hfill
\begin{minipage}{0.25\textwidth}
\begin{tabular}{|p{\textwidth}}
This is the third column.
\end{tabular}
\end{minipage}%
\end{document}
There are a couple problems:
- I'm getting underfull/overfull warnings.
- The equations are not broken up as nice as I'd like to in the first column.
- The second and third columns overlap.
- I'd like the separator lines go across the whole page.
- It's in portrait mode.
\documentclass{...}
and ending with\end{document}
.
