How to switch between two different marginparwidth size?

Question

I like this book layout stewartcalculus, so I want to mimic some of its layout. In this topic I want to start from the page number 5. The following is the screenshot: (hopely don't break the copyright :D)

The upper part has shorter marginparwidth compared to the Exercise part. I am interested how the author of this book modified the marginparwidth back and forth, from the main content to the exercise.

Thank you in advance.

EDIT 1:

Or he wrote it using softwares other than LaTeX ? InDesign or something like that?

Answer 1

In the Tufte-LaTeX document class, we achieve that affect by defining a fullwidth environment. The definition of this environment uses the changepage package (or an earlier version named chngpage). A simplified version looks like this:

\documentclass{article}

\usepackage{changepage}% provides the adjustwidth environment
\usepackage{multicol}% for multiple columns inside the fullwidth environment

% The following code should be used *after* any changes to the margins and
% page layout are made (e.g., after the geometry package has been loaded).
\newlength{\fullwidthlen}
\setlength{\fullwidthlen}{\marginparwidth}
\addtolength{\fullwidthlen}{\marginparsep}

\newenvironment{fullwidth}{%
  \begin{adjustwidth*}{}{-\fullwidthlen}%
}{%
  \end{adjustwidth*}%
}

\usepackage{lipsum}% provides dummy text

\begin{document}

\lipsum[1]

\begin{fullwidth}
  \begin{multicols}{2}
    \lipsum[2]
  \end{multicols}
\end{fullwidth}

\lipsum[3]

\end{document}

Answer 2

There are various ways to change the margins on-the-fly or to overwrite them.
If the exercises are in a box without page break you can use simply \hspace*:

\documentclass{article}
\usepackage{lipsum,multicol}
\begin{document}
\lipsum[1]

\vfill
\noindent\hspace*{-3cm}%
\begin{minipage}{\dimexpr\textwidth+3cm}
\begin{multicols}{2}
\lipsum[1]
\end{multicols}
\end{minipage}        
\end{document}

Answer 3

The document was turned into a PDF using Distiller, which I guess means it wasn't typeset using a Tex technology. I wonder if those formulae could have been generated using Framemaker's Equation Editor.

In Context, the narrower start-stop environment would be the way to do this:

\startnarrower[left=1.5in]
     Upper part
\stopnarrower
Exercises

The narrower can be use with negative values to narrow the margins, rather than the text.

Answer 4

The layout of the pages is somewhat reminiscent of some of the tufte-latex document classes. They both have the same wide margin, with notes, figures and tables, and tufte-latex classes do have a way to insert material that will use the full width of the page. I am sure Stewart did not use these, since his books predate tufte-latex, as far as I know.

Answer 5

how about something simple like that:

\documentclass[10pt]{book}
\usepackage{lipsum}
\usepackage[top=5cm,left=2cm,right=2cm,bottom=5cm,a4paper]{geometry}
% wide left margin environment
\newenvironment{foo}{\par\leftskip=4cm \rightskip=0cm}{\par}

\begin{document}
\begin{foo}
\section{plo}
\lipsum[5]\lipsum[5]
\section{plo}
\lipsum[5]\lipsum[5]
\end{foo}
\section*{Exercice}
\lipsum[1]
\begin{foo}
\section{plo}
\lipsum[5]\lipsum[5]
\section{plo}
\lipsum[5]\lipsum[5]
\end{foo}
\end{document}

Answer 6

Here is a hack on top of the tufte-book class in order to keep it simple. Two environments are defined one for oneside pages and another for double sided pages called adjustmargins use negative values to pull towards the page edges. The correct way is to redefine large sections of the class or even write one from scratch (I would do the latter as the tufte-class puts all captions and citations in the margins which is really not suited in this case). Code is rather long but prints a full page to see the possibilities. Code needs work. I normally code like a sketch, get as quickly as possible to what I want and then go back and re-factor. For example in a final version, I would code the button for answers either using hyperef or insdljs and redefine all page dimensions.
