General ⇒ Equations that take more than 1 page

[jhho]

Hi all,

I have series of equation that are being grouped using subequations. However these equations are long and it takes more than 1 page. I used the following code and end up with some equations couldn't be displayed (because LaTeX just try to squeeze all equations on a single page). Can anyone suggest a solution? Thank you very much.

\documentclass[11pt,a4paper]{article}
\usepackage{amsmath, amsthm, amssymb}

...

\begin{subequations}
\renewcommand{\theequation}{\theparentequation \roman{equation}}
\begin{eqnarray}
Eqn1 \\
Eqn2 \\
...
Eqn32
\end{eqnarray}
\end{subequations}

Hi jhho,

welcome to the board!
Don't use eqnarray, this is an obsolete environment and could give inconsistent spacing, use the align environment of amsmath instead. For more explanation see: eqnarray vs. align.
The align environment supports page breaking, you can use \allowdisplaybreaks or \displaybreak, those commands are documented by the amsmath user's guide in 3.9 Vertical spacing and page breaks in multiline displays.

Hi Stefan,

Thank you very much! It's working fine now.

Best regards
