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

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