equationsline-breaking
I have an equation long enough to occupy two lines.
I want to break it to improve readability. How can I break it?
\begin{equation}
F = \{F_{x} \in F_{c} : (|S| > |C|) \cap
(minPixels < |S| < maxPixels) \cap
(|S_{connected}| > |S| - \epsilon)
\}
\end{equation}
I want to break it in 3 lines after \cap. But \\ or \n didn't work.
I'd much prefer Jubobs's approach, but just to show another method, you can split into two lines the radicand:
\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{fourier}
\usepackage[left=3cm,right=3cm,top=2.5cm,bottom=2cm]{geometry}
\begin{document}
\[
V_{DABC}=\dfrac{1}{6}\cdot DA \cdot DB \cdot DC \cdot
\sqrt{
\begin{aligned}
1+&2\cos\widehat{ADB}\cos\widehat{BDC}\cos\widehat{ADC} \\
& -\cos^2 \widehat{ADB} -\cos^2 \widehat{ADC} -\cos^2 \widehat{BDC}
\end{aligned}
}
=\dfrac{2\sqrt{2}}{3}.
\]
\end{document}
I removed the unnecessary centered dots.
Setting the breakable portion in a \parbox of sufficient width allows you to break it at will as well as properly align the content:
\documentclass{article}
\usepackage{mathtools}
\usepackage[boxed,vlined,linesnumbered,noresetcount]{algorithm2e}
\begin{document}
\begin{algorithm}[tp]
\texttt{out} $\vcentcolon=$ \textsc{foo}($\texttt{x} \rightarrow \texttt{child[which]}$, $\langle 1,0,0,\texttt{old} \rangle$, $\langle 0,0,0,\texttt{new} \rangle$\;
\texttt{out} $\vcentcolon=$ \textsc{foo}(\parbox[t]{.6\linewidth}{%
$\texttt{x} \rightarrow \texttt{child[which]}$, \\
$\langle 1,0,0,\texttt{old} \rangle$, \\
$\langle 0,0,0,\texttt{new} \rangle$)\;}
\end{algorithm}
\end{document}
