Equation numbering with symbols

Postby dsbaero » Mon Jan 11, 2021 12:49 am

I can really use help on a rather unusual need in equation numbering.

Sometimes I like to end a proof with an equation. Normally I would use

\tag*{\mbox{\Large$\square$}}

to put a nice big square at the end of the line.

Now, I don't normally label any equation inside a proof that I don't refer to inside the proof since I view the proof as a kind of sealed box.

That aside, suppose I want to end the proof with an equation *and* number that equation. To do this, I would like to typeset:

f(x) = 0. (2.10)[]

where [] represents a typeset square to the right of the equation number at the right edge of the page.

I suppose I could manually use tag* but that would mess up the automatic equation numbering.

So my question is: How can I keep automatic equation numbering *and* put a box at the end of the line just to the right of the equation number?



Thanks!!!

Actually I would settle for placing a square out at the margin just below the equation number. When I use \hfill it skips a line. Any suggestions on how to pull the square up close to the equation number? Thanks
