# [Tex/LaTex] Using a big brace over multiple lines – multiple lines left of it

arraysbracesequationsmath-mode

I am super helpless, I wanna do the following:

Mathmode, 2 lines on the left, a brace over both (using array) and than I wanna have 3 lines on the right. A small example:

\begin{align*}
\left.
\begin{array}{l l}
&H_0 : \theta  \in \theta_0\\
&H_1: \theta \in \theta_1 \end{array}
\right \rbrace
\theta \in \Theta \theta_1 \cup \theta_0 = \Theta \\
\theta_1 \cap \theta_0 = \empty
\end{align*}


Whereever there is only a spaceholder \ i rather wish a new line.
Any idea how to do that?

The mathtools package provides an environment called rcases; it behaves pretty much like the cases environment of the amsmath package does except that the curly brace is set at the right-hand end.

The following code uses both an rcases and an array environment: \documentclass{article}
\usepackage{mathtools} % mathtools loads the amsmath package automatically
\begin{document}
$\begin{rcases} H_0: & \theta =\theta_0 \in \Theta_0\\ H_1: & \theta =\theta_1 \in \Theta_1 \end{rcases} \quad \begin{array}{r@{\;}l} % make space to RHS of \in and = symbols equal to that used for mathrel items \theta \in &\Theta \\ \Theta_0 \cup \Theta_1 = &\Theta \\ \Theta_0 \cap \Theta_1 = &\emptyset \end{array}$
\end{document}
