functions in word

[muhtar0101]

When exported to docx, mathematical formulas are converted well, but functions are converted as text. For example, in word, when writing a formula, after entering a function, press the space bar, and a window will appear, there we enter expressions inside the function. And it looks good. I would also like to add that I work at obsidian, and convert to docx often. As a mathematician, I would like to recognize \operatorname{tg} xor another like \arctg as a function, I apologize for the translation, thank you.

I tried entering sin x in the Word equation editor, and the resulting XML looks like this:

Pandoc's output, by contrast, is not wrapping the operator name in a m:func element.

So I think this is a place where pandoc's docx output could be improved. You could open an issue at jgm/texmath (that is the library that does the math), referencing this discussion.

I think the problem is that our math parser does not represent the notion of a "function application"; it has the notion of an operator name, but it doesn't separately represent what is the argument of that operator (here, 'x'). This seems to be needed for the output above -- unless m:fname can be used by itself (EDIT: it seems not).
