I am afraid that this issue should be fixed in Maple, don't they have
some issue tracker? The following version of your input compiles fine:
--------------------
\documentclass[11pt]{article}
\usepackage{amsmath,mathtools,amssymb}
\begin{document}
\begin{align*}
{\frac {1}{\sqrt { \left| y \right| }}}\mathop{\mathrm{d}y}&=
\mathop{\mathrm{d}x}\\
\int {\frac {1}{\sqrt { \left| y \right| }}}
\mathop{\mathrm{d}y}&= \int \mathop{\mathrm{d}x}\\
\begin{cases}-2\,\sqrt {-y} & y\leq 0\cr 2\,\sqrt {y} &
0<y\end{cases}&=x+C_{{1}}\\
\end{align*}
\end{document}

You should also try the LaTeX math + MathJax, but I doubt it will
support incorrect input.
