According to This preceding posting, I was experiencing some frustration over trying to typeset Math, for publication in EPUB2 format. EPUB3 format with MathML support was a viable alternative, though potentially hard on any readers I might have.
Well a situation exists in which either EPUB2 or MOBI can be used to publish typeset Math: Each lossless image can claim the entire width of a column of text, and each image can represent an entire equation. That way, the content of the document can alternate vertically between Text and Typeset Math.
In fact, if an author was to choose to do this, he or she could also use the Linux-based solutions ‘LyX’ , ‘ImageMagick’ , and ‘tex4ebook’ .
