# line breaking has no effect in doublespace

I am trying to break a doublespace content without any success.

\documentclass{article}
\usepackage{amsmath, amssymb, graphics, setspace}

\begin{document}

\begin{doublespace}
\noindent $$\left\{\left\{ aaa \right\}, \\ ~ \\ ~ \\ ~ \\ \left\{bbb\right\}\right\}$$
\end{doublespace}

\end{document}


The part {bbb} does not go to the new line as if \\ has no effect in doublespace

• this is not because of doublespace but because of iniline math – touhami Jun 29 '16 at 5:46
• @touhami, how can i fix it? – ar2015 Jun 29 '16 at 5:48

• @touhami, thanks but using split and align also gave me error – ar2015 Jun 29 '16 at 5:57
• @touhami, I used  \begin{split} and now the problem is fixed. – ar2015 Jun 29 '16 at 5:59
