I have 3 short equations which consume much vertical space, if each one is typeset in a separate line.
- How can I typeset them in one line in a "mathematically correct" way?
I do not necessarily need separate labels for each one of them: one label (and equation number would be enough)
\documentclass[11pt, a4paper]{scrbook}
\usepackage[ngerman]{babel}
\usepackage{array, amsmath}
\begin{document}
\begin{eqnarray}
x_{1} &= & \frac{A-A_{0}}{\frac{1}{2}\cdot \left( A_{\mathrm{A}} - A_{\mathrm{a}} \right)}
\label{exv:eqn:UmrechnungEingangsgroesse1} \\
x_{2} &= & \frac{B-B_{0}}{\frac{1}{2}\cdot \left( B_{\mathrm{A}} - B_{\mathrm{a}} \right)}
\label{exv:eqn:UmrechnungEingangsgroesse2} \\
x_{3} &= & \frac{C-C_{0}}{\frac{1}{2}\cdot \left( C_{\mathrm{A}} - C_{\mathrm{a}} \right)}
\label{exv:eqn:UmrechnungEingangsgroesse3}
\end{eqnarray}
\end{document}
Best Answer
First of all, Avoid
eqnarray
.You can use a normal
equation
environment and separate the equations with a\qquad
.(In my original answer I used an
align
environment, but this isn't really "correct", as that is meant for aligning equations over more than one line. As this only has one line, it is more appropriate to use anequation
environment, as commented by Andrew Stacey.)
