I have written an answer in Mathematics Stack Exchange: https://math.stackexchange.com/a/4215136/955104
So I just want to convert that answer into Word.
Thanks for any help
Mathpix Snip has the ability to 'Export to .docx', and also allows you to 'Copy MS Word'. Apparently the two give different things and I don't understand what 'Copy MS Word' gives. I also do not have any version of Word. But when I took a screenshot of nearly all your post with the app (its too long for one screenshot) I get
Clicking on 'Export to .docx' puts a
Doc1.docx in my
~/Downloads/ folder. When I open it with Apple Pages, the text is not sized correctly:
but on selecting all the text and changing the font size I see something reasonable:
There is an edit button in the screenshot that allows you to just paste $\rm\LaTeX$ code. Unfortunately, your post was not formatted in correct $\rm\LaTeX$, despite displaying correctly on this site. (Pasting your post into a template
.tex file shows 16 errors. For example, you cannot have new lines
\\ inside inline math mode
$...$.) This is because of the difference between $\rm\LaTeX$ and MathJax (and MathJax in my experience is more lenient.)
It is not a perfect copy of your post, e.g. Mathpix does not copy
\boxed correctly. I would suggest to avoid this anyway except perhaps for the final statement of the answer (and it seems you have a comment suggesting this). IMO it is better to stick to basic MathJax/$\rm\LaTeX$ commands unless necessary.
Unrelated to your specific query: Mathpix will not copy over any graphs or pictures you have included, which will require manual editing. Sometimes it reads posts wrongly anyway, so you should always read the result once over.
As of October 5th 2021 they have a "PDF to Word" option on the website. I haven't tried it; presumably you could print the website as a PDF, and give it a go. They say 20 pages a month are free.
1I feel almost like a shill, especially as there is a paid version of Mathpix, but I'm still happy with the free version at this moment. (And there is no affiliation.)
