Ok, using equation instead of \[ \] does not produce error with tex4ht

=========================
\documentclass[11pt]{book}
\usepackage{amsmath,mathtools,amssymb}
\begin{document}
\begin{equation}
   y \left( x \right)  = G\left(x, \frac{  \mathop{\mathrm{d}y}}{\mathop{\mathrm{d}x}}\right) \tag{1A}
\end{equation}
\end{document}
===========================

And it works in pdf also. so now I just need to change my program
and make it use equation instead of \[ \] everywhere from now on
and will not use \[ \] any more.

Not sure what other subtle differences there are between
equation and \[ \] but as long as it compiles with tex4ht, I am happy.
