Use an aligned environment inside equation : \documentclass{article} \usepackage{mathtools} \begin{document} \begin{equation}\label{eq:longeq} \begin{aligned}[b]% the number will be at b(ottom) \frac{dW}{d\lambda} = \sigma_{1}-\sigma_{2}%\nonumber = nk\Theta\times\Biggl(&\frac{1}{2}\left(2\lambd...

You can use TikZ to define your own line: \documentclass{scrartcl} \usepackage{tikz} \newcommand\myline[1][]{% \,\tikz[baseline]\draw[very thick,#1](0,-\dp\strutbox)--(0,\ht\strutbox);\,% } \begin{document} Text\myline Text\myline[dashed]Text\myline[dotted] \end{document} myline.png Best regards Elke

Set the tree inside a tikzpicture. Then you can use the normal tikz syntax to draw the arrow: \documentclass{minimal} \usepackage{tikz} \usetikzlibrary{arrows} \usepackage{tikz-qtree} \begin{document} \begin{tikzpicture} \Tree [.S [.NP [.\node(subj){subj$_i$}; ] ] [.VP [.V verb ] [.NP [.\node(t){t$_...

You can add circle nodes on the right side using a foreach loop: \foreach \y in {0,3,6} \foreach \i in {1,2,3} \node[circle,fill,inner sep=0.5*\pgflinewidth,xshift=\i*0.5em] at (13,\y){}; circuitikz1.png Code: \documentclass[border=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{cir...

There are four columns instead of three in the last two rows. And you have to use {\textbf{Siunitx3}} \documentclass{beamer} \usepackage{siunitx} \usepackage{lmodern} \begin{document} \begin{frame} \centering \begin{tabular}{rcS[table-number-alignment = center, table-figures-integer=5]} \textbf{Righ...
