Math & Science ⇒ Multi-line right brace

[AkkawiRS]

Hey guys, I'm writing a 3-line equation and need a brace to join them all on the right side. I know I can use "\begin{cases}" but that gives me a brace on the left side. What do you propose?

Take a look at the empheq package from the mh bundle.

What's wrong with this?

Code: Select all

\begin{equation}
  f(x) = \left\{
  \begin{array}
    1 & x > 0 \\
    0 & x = 0 \\
    -1 & x < 0
  \end{array}
  \right.
\end{equation}

It still has a brace on the left side. And the OP wants a brace at the right side. Furthermore it is unclear if the OP wants that brace beside equations which are numbered separately.

I don't think he wants to number them, if what he writes is correct. (I'm taking the fact that he states he could use the {cases} environment into consideration.) He could do it this way:

Code: Select all

\left.\begin{aligned}
Equation 1 \\
Equation 2 \\
Equation 3
\end{aligned}\right\rbrace

Code: Select all

\begin{equation}
   f(x) = \left\{
   \begin{array}{cc}
     1 & x > 0 \\
     0 & x = 0 \\
     -1 & x < 0
   \end{array}
   \right.
\end{equation}
