Can't be certain, but I'd guess that these are occurring within
captions for figures or tables, or section-headings.
Look inside the .toc and .aux files.
Does \@mathbf occur there ?
If so, find the \caption or sectioning command,
and use \protect\mathbf at these places.
Then rerun LaTeX to fix the auxiliary files.
Now LaTeX2HTML should work correctly for this document.

This expansion of \cos --> \mathop {\mathgroup \symoperators cos}\nolimits
was done by LaTeX, not by LaTeX2HTML.
It can get into LaTeX2HTML only by the \write mechanism, putting information
into .toc, .lof .aux or similar files.
Same fix: use \protect\cos at that point.
Rerun LaTeX, then rerun LaTeX2HTML.

No, because this doesn't involve any auxiliary files.
Hope this helps,
