I dont think newlines are supported this way in tex. Here's an example:
\documentclass[]{article}
\begin{document}
$a=e^{i\pi}\\x=y$
$$a=e^{i\pi}\\x=y$$
\begin{eqnarray}
a & = & \frac{e^{i\pi}}{e^{-i\pi}} \\
& = & e^{i2\pi}
\end{eqnarray}
\end{document}
The first treats the newline as if it occurred in regular text mode, the
second ignores the newline entirely, and the third is intelligent enough to
do what it should.
