    Ví dụ, để hiển thị hàm

    \[
    f(x)=
    \left\{
    \begin{array}{l l l}
    x^2+1 & \textrm{ nếu } & x \geq 1 \\
    x+1 & \textrm{ nếu } & x \end{array}
    \right.
    \]

    ta gõ:

    \begin{equation}
    f(x)=
    \left\{
    \begin{array}{l l l}
      x^2+1 & \textrm{ nếu } & x \geq 1 \\
      x+1 & \textrm{ nếu } & x < 1
    \end{array}
    \right.
    \end{equation}

      Tôi thường làm như sau:

      \begin{equation}
      f(x) = \begin{cases}
                x^2+1 & \text{ nếu } x \ge 1 \\
                x+1 & \text{ nếu } x <1
             \end{cases}
      \end{equation}
