How to remove chapter numbering without removing it from table of contents

Question

It seems I have spent two days trying to find out the solution to my problem. I have just finished typing my M.Sc thesis using Latex (MIKTEX 2.9). Unfortunately, all my chapters begin with the chapter number at the top left corner of a page. My supervisor asked me to remove that numbering of the chapters without removing them from the table of contents.

I have tried my best to do that but I failed. The last attempt I made is \chapter*{chapter title}, the moment I compiled my work, I found out that it began sectioning from 0.1, 0.2, and so on, which I don't like.

I have this code inside my thesis:

\chapter*
{\quad \quad \quad \quad \quad\quad \large{CHAPTER ONE}}
\addcontentsline{toc}{chapter}{CHAPTER ONE}

%Introduction}{}
\pagenumbering{arabic}
\onehalfspacing
\begin{center}
\textbf{\large \quad INTRODUCTION}
\end{center}

\section{Introduction} This chapter gives a brief highlight on the concept of the Newton and quasi-Newton methods for solving nonlinear system of equations. The chapter contains motivation of the study, the aim and objectives, scope and limitations, methodology of the research. It includes some basic fundamentals and definitions of some basic terms.

After compiling, it gives me this:

CHAPTER ONE

INTRODUCTION

0.1 Introduction
This chapter gives a brief highlight on the concept of the Newton and quasi-
Newton methods for solving nonlinear system of equations. The chapter contains
motivation of the study, the aim and objectives, scope and limitations, methodol-
ogy of the research. It includes some basic fundamentals and definitions of some
basic terms.

NB: Please observe how the section "Introduction" is numbered. I want it to be numbered 1.1 not 0.1.

Answer 1

By adding \setcounter{chapter}{n} before the nth chapter seems to fix the numbering of subsections issue. Also though, you have to reset the numbering of sections. An easy way to do this would to just define a new command. For example:

\documentclass{report}
\newcommand{\mychapter}[2]{
    \setcounter{chapter}{#1}
    \setcounter{section}{0}
    \chapter*{#2}
    \addcontentsline{toc}{chapter}{#2}
}
\begin{document}
\tableofcontents
\mychapter{0}{Acknowledgments}
\mychapter{1}{Introduction}
\section{Introduction}
\section{Further Introduction}
\mychapter{2}{Experiments}
\section{Experiment One}
\section{Experiment Two}
\end{document}

Answer 2

You can do something as is done in here. Use code similar to the following:

\documentclass{report}
\begin{document}
\tableofcontents
\chapter*{Acknowledgments}
\addcontentsline{toc}{chapter}{Acknowledgments}
\chapter*{Introduction}
\addcontentsline{toc}{chapter}{Introduction}
\chapter{Experiments}
\chapter{Conclusion}
\end{document}

The idea is to use \chapter*{} for unnumbered chapters and then add them to the toc explicitly with the \addcontentsline. Which gives this result:

Answer 3

If I read that correctly, you want chapters to have numbers. These numbers should be shown in the ToC. But the numbers should not be printed in the chapter heading. This can be achieved with the titlesec package:

\documentclass{report}
\usepackage{titlesec}

\titleformat{\chapter}
  {\Large\bfseries} % format
  {}                % label
  {0pt}             % sep
  {\huge}           % before-code

\begin{document}
\tableofcontents
\chapter{Acknowledgments}
\chapter{Introduction}
\section{Introduction}
\section{Further Introduction}
\chapter{Experiments}
\section{Experiment One}
\section{Experiment Two}
\end{document}

The ToC then looks like

while the chapter heads in the text look like

Answer 4

I don't think that you want to remove the numbering: You want to use words (one, two) instead of numbers in the heading. This can be done (for english) e.g. with the numname package. The exact code depends on your class, here is an example for book:

\documentclass{book}
\usepackage{numname}
\makeatletter
%Redefine chapterheading:
\def\@makechapterhead#1{%
  \vspace*{50\p@}%
  {\parindent \z@ \raggedright \normalfont
    \ifnum \c@secnumdepth >\m@ne
      \if@mainmatter
        \huge\bfseries \@chapapp\space \numtoName{\c@chapter}
        \par\nobreak
        \vskip 20\p@
      \fi
    \fi
    \interlinepenalty\@M
    \Huge \bfseries #1\par\nobreak
    \vskip 40\p@
  }}
\makeatother
\begin{document}
\tableofcontents
\chapter{abc}
\section{abc}
\end{document}

Answer 5

None of the other solutions worked for me. Here's what worked:

\tableofcontents

\phantomsection
\chapter*{Introduction}
\addcontentsline{toc}{chapter}{Introduction}

This is the beginning

Note the use of \phantomsection. Thanks to this old thread on LaTeX.org from '08.
