I'd like to typeset equations like:
z = (x+y)^2
= x^2 + 2xy + y^2
The \TeX book has a nice concept called \eqalign which lines up
equations so the = comes vertically aligned. It doesn't work in
LaTeX.
Any ideas on how it's done?
Thanks,
-ans.

The simplest way is to use the eqnarray* environment, separating the LH, the equals sign, and the RH with "&" and separating lines with "\\": \begin{eqnarray*} z & = & (x+y)^2 \\ & = & x^2 + 2xy + y^2 \end{eqnarray*} If you need to do more interesting alignment, or embed these equations within higher-level math constructs, you should look at the documentation for the "array" environment, which is what eqnarray* is based on. -- =============================================================================== Pete Halverson INET: halverson@crd.ge.com GE Corporate R&D Center UUCP: uunet!crd.ge.com!halverson Schenectady, NY
