I have a long math formula and I can't fit it on one page. How do In put such fomula in two lines? Example:
F=sqrt(............................. ..................) ?
use the multline environment of amsmath, then you have exactly what you want (it's supported by LyX). For more infors about all math environments look at http://www.perce.de/LaTeX/math/Mathmode.TeX.pdf
