I would like to change equation numbering like: (1a) (1b) (1c). How should I do this? My code is like this:

\begin{equation}
first equation with number(1a)
\end{equation}
\begin{equation}
first equation with number(1b)
\end{equation}
\begin{equation}
first equation with number(1c)
\end{equation}

  • Welcome to TeX.SX! You should make clear what the fixed number means: is it the section/chapter number or is it the “global number” of the set of equations? In the latter case, follow the link shown by Werner; otherwise \renewcommand{\theequation}{\thesection\alph{equation}} is the way to go. – egreg Oct 19 '15 at 17:23
  • Do you want to do this globally, or do you need subeqations? – Johannes_B Oct 19 '15 at 17:30
  • I want to do this globally. Thanks for your help – fariba milani Oct 20 '15 at 14:42
