# Fixing formatting errors created by long eqnarrays

I'm writing a paper in which I have long eqnarrays, many of them 10 lines or longer. Since TeX seems to not want to page-break these equations, this results in weird formatting, eg pages that have large amounts of whitespace and not much actual text. Is there any way to force TeX to page-break eqnarray equations in a natural way?

Welcome to TeX.SE. Here is a related question that might be helpful: custom alignment of columns in align environment –  Peter Grill Jan 27 '12 at 18:10
Don't use the eqnarray environment; instead, load the amsmath package and use its align environment. To allow page breaks, issue the statement \allowdisplaybreaks. –  Mico Jan 27 '12 at 18:19
