roman numbering for few sections [closed]

Question

I have some attachments in my document and I would like to number them with a roman style.

How can I do this?

I tried:

  \documentclass[12pt,a4paper,oneside]{book}
  \begin{document}

  \chapter*{Atachments}
  \renewcommand{\thesection}{\Roman{section}}
  \section{my section}

  \end{document}

EDIT Before the chapter* of attachments, I have an appendix with sections A.1, A.2, A.3.

So, the number of the first section of attachments is IV instead of I.

How can I correct this?

Answer 1

You can use \setcounter{section}{0}:

  \documentclass[12pt,a4paper,oneside]{book}
  \begin{document}
  \appendix
  \chapter{One}
  \section{one}  
  \chapter*{Attachments}
  \setcounter{section}{0}
  \renewcommand{\thesection}{\Roman{section}}  
  \section{my section}
  %
  \end{document}
