Math & Science ⇒ Placing rhs parenthesis on set of equations?

[Mark65]

I would like to have on the RHS a } parenthesis with numbering of the following equations (load amsmath package):

Code: Select all

\begin{align} \label{diffeq2}
\begin{split}
\frac{\partial A_{1}(z)}{\partial z}= i c A_{D}(z) \, , \vspace{2mm} \\
\frac{\partial A_{D}(z)}{\partial z}= i c A_{1}(z) + i c A_{2}(z) \, , \vspace{2mm} \\
\frac{\partial A_{2}(z)}{\partial z}= i c A_{D}(z) \, .
\end{split}
\end{align}

I tried with \rbrace but could get any decent result. Can anyone help?

Hi Mark,

welcome to the board!

You could use the aligned environment:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}\label{diffeq2}
  \left.
  \begin{aligned}
    \frac{\partial A_{1}(z)}{\partial z}&= i c A_{D}(z) \, , \vspace{2mm} \\
    \frac{\partial A_{D}(z)}{\partial z}&= i c A_{1}(z) + i c A_{2}(z) \, , \vspace{2mm} \\
    \frac{\partial A_{2}(z)}{\partial z}&= i c A_{D}(z) \, .
  \end{aligned}
  \right\rbrace
\end{equation}
\end{document}

Ahhh... ok. Thanks a lot.
