I'd like to know if it's possible to insert a horizontal line whose width is the same as the page content's width.
Example:
Code: Select all
\documentclass[]{article}
\usepackage[brazil]{babel}
\usepackage[latin1]{inputenc}
\usepackage{amsmath,amscd,amsthm}
\pagestyle{empty}
\begin{document}
\center
anything
\[x=a_1+a_2+a_3+a_4+a_5+a_6+a_7+a_8+a_9+a_{10}+a_{11}\]
Text..
\noindent\hrulefill %to be changed
Text..
\newpage
\[x=\sum_{p=1}^{11}a_p\]
text text text text text
\noindent\hrulefill %to be changed
text
\end{document}
Which LaTeX commands should I use to get this? (I used an image editor

Is it possible?
Thank you!
