I am trying to write bar symbol with some alphabets inside \begin{equation} \end{equation} like this,


H \bar{k} 


I have more than one alphabet to give bar. I've showed only one though.

It shows a lot of error as it is in out of math mode. How do I give bar in this equation mode?

  • By alphabet do you mean a single letter? And Welcome to TeX.SE.

The command \= is the text mode equivalent of \bar.
