What is a workaround? comment on the above question says not to use align for single equation and so I use \[ \] for single equation but want to tage it also.
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. --Nasser
