Equation array troubles [closed]

I have a problem and I've been searching forever for a fix to it.

I have three equation arrays that are huge. They all have about 10 to 20 equations.

LaTeX does not seem to want to split up the equation arrays onto different pages. A consequences of this is that I have huge black vertical spaces separating the equation arrays just so every array is one just one piece of paper. How do I get rid of these black, empty, vertical spaces?

• Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – karlkoeller Nov 20 '13 at 19:48
• If you're using eqnarray, then don't. See eqnarray vs align. – Werner Nov 20 '13 at 19:57
• Are you using the eqnarray or the align environment? Please advise. If it's the latter, you could use the instruction \allowdisplaybreaks to allow page breaks after explicit line breaks. If you're using eqnarray: Don't do it... – Mico Nov 20 '13 at 19:58
• To expand on what @Werner said, look at the documentation for the amsmath package, section 3.9: “Vertical spacing and page breaks in multiline displays”. – Harald Hanche-Olsen Nov 20 '13 at 19:59
• black vertical spaces? this sounds like the equations are too wide as well as too many of them. a "minimal" example (although possibly not too minimal in this case, so let's try "typical") would really be helpful. – barbara beeton Nov 27 '13 at 15:21

\begin{align*}

you could then use \tag{no} to manually no. them. You'll need \usepackage{mathtools, amssymb} though. it should automatically break to a new page. hope it helps ... = should be replaced by you symbol.
