Say I am typing the following:

f(x) &= absuc \tag{First tag} \\
     &= abshgi \tag{Second tag}. 

This outputs the following: enter image description here

However, I am trying to find a way to get the full stop (period) AFTER the close bracket of the tag (my supervisor is very picky with regards to placement of full stops). How can I get it to do that?

    Sorry for you. But it doesn't make any sense. :(

  • @egreg - I can't seem to think it's possible either :( . I guess I'll just have to "fake it" by manually inserting spaces instead of tags.

I sympathize with you.




f(x) &= absuc \tag{First tag} \\
     &= abshgi \tag[.]{Second tag}\label{X}

  • The punctuation in the optional argument will be in the margin.
