Math & Science ⇒ How can I make a page break within an align environment?

[Mini]

When I'm using \begin{align*} etc if the set of equations to be aligned are too long then the WHOLE environment is displayed on the next page. How can I make it continue on to the next page?

Thanks

Hi Mini,

you could use

Code: Select all

\allowdisplaybreaks[1]

in your preamble. Instead of 1 you could use 2, 3 or 4 to increase permissiveness. Another command, which you could use within the formula right before \\, is \displaybreak. It also understands an optional argument with values 1, ..., 4.
If you would like to read more: both commands are explained in the amsmath user's guide.

Thanks for that. One more question regarding align.

I've noticed that whenever I used the align environment, it intents it. How would I make it so that it's in alignment with the text on the page?

Thanks again.

EDIT: Another (last) question, whenever I used enumerate and I have the align environment on the first line, the environment starts from the next line. How would I make it so that it starts from the first line (ie. the line with the number on it)?

Thanks again

You probably use the fleqn option. Then you may modify the length \mathindent:

Code: Select all

\setlength{\mathindent}{0pt}

It doesn't have to be the last one.

Within an enumerate item, you could use the aligned environment instead. For example, with top alignment:

Code: Select all

\item $\begin{aligned}[t] ... \end{aligned}$

aligned works within inline math mode, thus there's no paragraph break.
