# Section numbering of equations without \section [closed]

I want to use the section numbering in the equations like (1.1), (1.2), ... (3.2). But I don't want to use \section command. How can I do this?

• Welcome to TeX.SX! Can you expand your question adding some more detail? If there's no section, what should the first number mean? – egreg Jun 1 '13 at 11:08

# Remarks

You might want to use the \numberwithin directive, like

\numberwithin{equation}{section}


# Implementation

\documentclass{scrartcl}
\usepackage{amsmath,amssymb}
\pagestyle{empty}
\numberwithin{equation}{section}
\begin{document}
\section{First section}
$$\hat{f}(\omega) = \frac{1}{\sqrt{(2 \pi)^n}} \int_{\mathbb{R}^n} f(t) \, \mathrm{e}^{\mathrm{i} \omega t} \, \mathrm{d}t$$
\end{document}
