The exercise is split in parts with the +%command |ExePart|. +% +%The environment \texttt{Exercise} can be stared (no number is +%typeset). The options of these commands are described in section +%\ref{sec:option}. The layout of exercises can be customised in many +%way: see section \ref{sec:custom}. +% +%It is common to have a long list of exercise to typeset, and the usage +%of the |Exercise| environment could be cumbersome. Another +%environment is available: the |ExerciseList| environment. +% +%\medskip +% +%\noindent \fbox{\begin{minipage}[t]{.95\textwidth} +%\begin{ExerciseList} +% \Exercise[label={ex:two}] Discuss the convergence or divergence of $ +% \left[1 + \sin \left(\frac1{an}\right)\right]^{bn}$ +% where $a$ and $b$ are two parameters. +% +% \Exercise Discuss the convergence or divergence of $ +% n^{\frac{(-1)^n}{n}} - 1$. +% +% \Exercise* Discuss the convergence or divergence of $ +% \frac{(-1)^n}{n+(-1)^n}$. +% +% \Answer[ref={ex:two}] $ \displaystyle \lim_{n\rightarrow +% +\infty} \left[1 + \sin \left(\frac1{an}\right)\right]^{bn}= {\mathrm{e}}^{\frac{b}{a}}$ +% +%\end{ExerciseList} +%\end{minipage}} +% +%\medskip +% +%\begin{verbatim} +%\begin{ExerciseList} +% \Exercise[label={ex:two}] Discuss... +% \Exercise Discuss... +% \Exercise* Discuss... +% \Answer[ref={ex:two}] $...$ +%\end{ExerciseList} +%\end{verbatim} +% +%This example show two new commands: |\Exercise*| (for an exercise +%without number) and |\Answer|.

The default behaviour is to show both the exercises +% and the answers. +% +% +% \item[|exerciseonly|] is a synonym of |noanswer|. +% +% \item[|answeronly|] is a synonym of |noexercise|. +% +% \item[|nothing|] hide answers and exercises (synonym of +% |noanswer| and |noexercise|). +% +% \item[|answerdelayed|] save the answers instead of typeset +% them. The answers can be included later in the document with the +% command |\shipoutAnswer|. More precisely, the answers are stored +% in a vertical box. When |\shipoutAnswer| is encountered, this box +% is emptied and its contents is placed in the main vertical +% list. The answers defined later are placed in this emptied +% vertical box. In this way, you can have many group of answers in +% the same document. +% +% \item[|exercisedelayed|] saves the exercises instead of +% typeset them. The exercises can be included later with the command +% |\shipoutExercise|. +% +% \item [|lastexercise|] if no references is given for an +% answer, then the answer is supposed to refer to the last +% exercise (see section \ref{sec:lastexercise}). +% +%\end{description} +% +% +%\section{Commands} +% +%\label{sec:option} +% +%\subsection{Exercises and answers} +% +% +%\begin{decl} +% |\begin{Exercise}| \oarg{key val list} ... |\end{Exercise}| \\ +% |\begin{Exercise*}| \oarg{key val list} ... |\end{Exercise*}| +%\end{decl} +% +%\DescribeEnv{Exercise}\DescribeEnv{Exercise*} +%The |Exercise| environment is used to typeset just one exercise.

They are all optional. +%\begin{description} +% \item[|label|] The label of the exercise. This label can be +% used later in cross-reference, or to link an answer to this +% exercise. +% \item[|title|] The title of the exercise. It will be available +% later with the command |\ExerciseTitle|. +% \item[|difficulty|] The difficulty of the exercise (a number). +% It will be available later with the counter +% |\ExerciseDifficulty|. +% \item[|origin|] The origin of the exercise. +% It will be available later with the command |\ExerciseOrigin|. +% \item[|name|] In document, exercises can have multiple +% denomination, like problem, exam, or even question. This key +% allows to change the denomination. +% \item[|counter|] Use the given counter to number this +% exercise. Here, \marg{counter} must be a pre-defined counter. +% \item[|number|] Use the given number for the exercise. In +% fact, this number is a string, so you can number the exercise +% with letters. +%\end{description} +% +%As an example, with the default definitions, the following code: +%\medskip +%\begin{verbatim} +%\begin{Exercise}[title={Euler's constant}, difficulty=2, +% origin={P.Paelw}] +%\end{Exercise} +%\end{verbatim} +%\noindent will give \par \medskip +%\index{example} +%\noindent \fbox{\begin{minipage}[t]{.95\textwidth} +%\begin{Exercise}[title={Euler's constant}, difficulty=2, +% origin={P.Paelw}] +%\end{Exercise} +%\end{minipage}} +% +%\DescribeEnv{Problem} +%It is possible to define different type of exercise. For example, +%you can define a |Problem| environment with the two lines: +%\begin{verbatim} +% \newcounter{Problem} +% \newenvironment{Problem}{\begin{Exercise}[name={Problem}, +% counter={Problem}]} +% {\end{Exercise}} +%\end{verbatim} +%Anyway, all type of exercise will have the same layout in the document. +% +%\begin{decl} +% |\begin{Answer}| \oarg{key val list} ... |\end{Answer}| +%\end{decl} +% +%\DescribeEnv{Answer} +%The |Answer| environment is used to typeset the answer of an +%exercise. To determine which the exercise this answer is attributed +%to, you can use the two following keys. +% +%\vspace*{-\baselineskip} +%\index{options>of \texttt{Answer}} +%\index{keys>of \texttt{Answer}} +%\begin{decl} +%|ref|=\marg{string}\\ +%|number|=\marg{string} +%\end{decl} +%This is the description of these keys: +%\begin{description} +% \item[|ref|] a \LaTeX\ reference. \emph{Must} correspond to the |label| +% key of an exercise. +% \item[|number|] if the answer refers to an exercise in +% another document, you can set the number of the exercise with this +% key. It is in fact a string. +%\end{description} +% +%\label{sec:lastexercise} If the package is loaded with the option +% |lastexercise| and if no |ref| and no |number| key is given, then +% the last exercise is taken as a reference for the answer. +% +%If no |ref| and no |number| key is given and the option |lastexercise| +%is not activated, a Package Warning is displayed. +% +%\begin{decl} +% |\begin{ExerciseList}| \\ +% \quad |\Exercise|\oarg{key val list} \\ +% \quad |\Answer|\oarg{key val list} \\ +% |\end{Exercise}| +%\end{decl} +% +%\DescribeEnv{ExerciseList} +%The |ExerciseList| environment is a convenience to typeset a list of +%small exercises. In |ExerciseList|, everything between two |\Exercise| +%or |\Answer| tags is interpreted as the body of an exercise (or an +%answer). +% +%\DescribeMacro{\Exercise} +%\DescribeMacro{\Exercise*} +%\DescribeMacro{\Answer} +%The command |\Exercise| inside |ExerciseList| accepts the same keys +%than the |Exercise| environment. The command |\Answer| inside +%|ExerciseList| accepts the same keys than the |Answer| environment and +%behaves in the same way. +% +%\subsection{Parts and questions} +% +%\begin{decl} +% |\ExePart|\oarg{key val list} \\ +% |\ExePart*|\oarg{key val list} +%\end{decl} +%\DescribeMacro{\ExePart} +%\DescribeMacro{\ExePart*} +%It is common to split large exercise in parts: it is the purpose of +%the |\ExePart| command. +%\index{options>of \texttt{\bslash ExePart}} +%\index{keys>of \texttt{\bslash ExePart}} +%The keys |title|, |name| and |difficulty| are +%available for this command. +% +%For example, a non-numbered preliminary part is obtained with +%\begin{verbatim} +% \ExePart*[name={Preliminary}] +%\end{verbatim} +% +%\begin{decl} +% |\Question|\oarg{key val list}\\ +% |\subQuestion|\oarg{key val list}\\ +% |\subsubQuestion|\oarg{key val list} +%\end{decl} +%\DescribeMacro{\Question} +%\DescribeMacro{\subQuestion} +%\DescribeMacro{\subsubQuestion} +%These three commands define the hierarchy of questions. A +%|\subsubQuestion| cannot be preceded by a |\Question| or a +%|\begin{Exercise}|. A |\subQuestion| cannot be preceded by a +% |\begin{Exercise}|. If one of these cases is detected, a Package +% Error is displayed. +% +%\index{options>of \texttt{\bslash Question}} +%\index{keys>of \texttt{\bslash Question}} +%\index{options>of \texttt{\bslash subQuestion}} +%\index{keys>of \texttt{\bslash subQuestion}} +%\index{options>of \texttt{\bslash subsubQuestion}} +%\index{keys>of \texttt{\bslash subsubQuestion}} +%Two keys are available for these commands: |title| and |difficulty|. +% +%\begin{decl} +% |\ExeText| +%\end{decl} +%\DescribeMacro{\ExeText} +%The text following this command has the same status that the first +%indications of the exercise. So, the next level of the hierarchy must +%be a |\ExePart| or a |\Question|. +% +% +%\subsection{Extra stuff} +%\DescribeMacro{\marker} +%\DescribeMacro{\DifficultyMarker} +%The difficulty of an exercise is represented by a certain amount of +%stars. The command |\marker| is used to typeset the difficulty of an +%exercise. +%\begin{verbatim} +% \marker<symbol><counter> +%\end{verbatim} +%displays |<symbol>| repeated |<counter>| times. For example |\marker*2| +% gives **, and |\marker+{14}| gives ++++++++++++++ +% +% By default, the difficulty is symbolized by star. You can customise +% this by redefining the command |\DifficultyMarker|. +% +%\section{Customisation} +% +%\label{sec:custom} +% +%\subsection{Internationalisation} +% +%\begin{decl} +%|\ExerciseName|\\ +%|\ExerciseListName|\\ +%|\AnswerName|\\ +%|\AnswerListName|\\ +%|\ExePartName|% +%\end{decl} +%\DescribeMacro{\ExerciseName} +%\DescribeMacro{\ExerciseListName} +%\DescribeMacro{\AnswerName} +%\DescribeMacro{\AnswerListName} +%\DescribeMacro{\ExePartName} +%\DescribeMacro{\ExePartListName} +%These commands store various hard-wired string. |\ExerciseListName| +%is used in the |ExerciseList| environment: it is possibly an +%abbreviation of the word ``Exercise". +% +%\textsf{Exercise.sty} automatically detects the usage of +% \textsf{babel} and translate these terms in the language loaded... +% if I (the author) know the translation! As my skills in foreign +% language are quite weak, only English and French are currently +% supported. +% +%If you sent me the translations in your language, I will be happy to +%add them in the package. Anyway, you can redefine these +%commands (with a |\renewcommand|). +% +%\subsection{Layout} +% +%\subsubsection{Exercises, answers and parts} +% +%For the layout of the exercises, two levels of customisation are +%available. First, you can customise the way the informations will be +%typeset, and then you can customise the way these pieces of +%informations are typeset together. +% +%\begin{decl} +% |\ExerciseHeaderTitle| \\ +% |\ExerciseHeaderDifficulty| \\ +% |\ExerciseHeaderOrigin|\\ +% |\ExerciseHeaderNB| +%\end{decl} +%\DescribeMacro{\ExerciseHeaderTitle} +%\DescribeMacro{\ExerciseHeaderDifficulty} +%\DescribeMacro{\ExerciseHeaderOrigin} +%\DescribeMacro{\ExerciseHeaderNB} +%These commands are used to typeset the corresponding information: +%\\ |\ExerciseHeaderTitle| corresponds to the |title| key, \\ +%|\ExerciseHeaderDifficulty| to the |difficulty| key, +%|\ExerciseHeaderOrigin| to the |origin| key and |\ExerciseHeaderNB| to +%the number of the exercise. +% +%In these commands, you specify the fonts to use, the space around the +%information, some symbols (like dash or dot) you want to put here, and +%so on. If the key is not present in the definition of the exercise, +%then the corresponding part of the header will be emptied by the package. +% +%For example the default definition of |\ExerciseHeaderTitle| is +%\begin{verbatim} +% \newcommand{\ExerciseHeaderTitle}{\quad---\quad\ExerciseTitle} +%\end{verbatim} +%If an exercise has a title, then this title will be displayed preceded +%by an emdash (as you can see in exercise \ref{exe:ex1} of this +%document). If an exercise doesn't have a title, then this command is +%set to nothing (precisely to |{}|) during the exercise. +% +%These commands can be redefined with a |\renewcommand|. You don't have +%to worry about the ``undefinition" mechanism: the package manages that +%by itself. +% +%\begin{decl} +% |\ExerciseHeader| \\ +% |\ExerciseListHeader| +%\end{decl} +%\DescribeMacro{\ExerciseHeader} +%\DescribeMacro{\ExerciseListHeader} +%When the layout of all the elements has been fixed, they are collected +%in the |\ExerciseHeader| command (or in |\ExerciseListHeader|). +%Here, you specify the way the different elements are mixed +%together. +% +%The default definition of |\ExerciseHeader| is +%\begin{verbatim} +% \newcommand{\ExerciseHeader}{\centerline{\textbf{\large +% \ExerciseName\ExerciseHeaderNB\ExerciseHeaderTitle +% \ExerciseHeaderOrigin\medskip}}} +%\end{verbatim} +%\noindent which displays all the informations in a centered line, using +%a large bold default font. +% +%\begin{decl} +% |\AnswerHeader| \\ +% |\AnswerListHeader| +%\end{decl} +%\DescribeMacro{\AnswerHeader} +%\DescribeMacro{\AnswerListHeader} +%The same mechanism is implemented for the answers. +%|\AnswerHeader| and |\AnswerListHeader| specifies the way the header +%of answers are typeset. In the definition of these commands, you can +%use freely the informations of the related exercise. For example, this +%is the default definition of |\AnswerHeader|: +% +%\begin{verbatim} +% \newcommand{\AnswerHeader}{\medskip\centerline{\textbf{ +% Answer of \ExerciseName\ \ExerciseHeaderNB}\smallskip}} +%\end{verbatim} +% +% +%\begin{decl} +% |\ExePartHeaderTitle| \\ +% |\ExePartHeaderDifficulty| \\ +% |\ExePartHeaderNB|\\ +% |\ExePartHeader|\\ +% |\ExePartListHeader| +%\end{decl} +%\DescribeMacro{\ExePartHeaderTitle} +%\DescribeMacro{\ExePartHeaderDifficulty} +%\DescribeMacro{\ExePartHeaderNB} +%\DescribeMacro{\ExePartHeader} +%\DescribeMacro{\ExePartListHeader} +%The same kind of customisation is available for the |\ExePart| +%command: |\ExePartHeaderTitle|, |\ExePartHeaderDifficulty| and +%|\ExePartHeaderNB| \\ control the way the title (|\ExePartTitle|), the +%difficulty (|\ExePartdifficulty|) and the number (|\theExePart|) of +%the part are displayed. +% +%These pieces are collected in the command |\ExePartHeader| or +%\\ |\ExePartListHeader|. +% +% +% +%\subsubsection{Questions, sub-questions and sub-sub-questions} +% +%The layout of the questions is a little more rigid. Somehow, it can be +%customised. +% +%\begin{decl} +% |\QuestionHeaderTitle| \\ +% |\QuestionHeaderDifficulty| \\ +% |\QuestionHeaderNB| +%\end{decl} +% +%\DescribeMacro{\QuestionHeaderTitle} +%\DescribeMacro{\QuestionHeaderDifficulty} +%\DescribeMacro{\QuestionHeaderNB} +%\DescribeMacro{\subQuestionHeaderTitle} +%\DescribeMacro{\subQuestionHeaderDifficulty} +%\DescribeMacro{\subQuestionHeaderNB} +%\DescribeMacro{\subsubQuestionHeaderTitle} +%\DescribeMacro{\subsubQuestionHeaderDifficulty} +%\DescribeMacro{\subsubQuestionHeaderNB} +%These commands plays the same role that the corresponding command +%relating to exercises. But here, no |\QuestionHeader| is defined. +% +%The |subQuestion| and |subsubQuestion| versions of these commands are +%also defined. +% +%All of these commands can be changed using |\renewcommand|. +% +% +%\subsection{Lengths} +% +%\begin{decl} +% \begin{tabular}{llll} +% |\Exesep| & |\Exetopsep| & |\Exeparsep| & +% |\Exepartopsep| \\ +% |\Exeleftmargin| & |\Exerightmargin| & |\Exelabelwidth| +% & |\Exelabelsep| +%\end{tabular} +%\end{decl} +%\DescribeMacro{Exesep} +%\DescribeMacro{Exetopsep} +%\DescribeMacro{Exeparsep} +%\DescribeMacro{Exepartopsep} +%\DescribeMacro{Exeleftmargin} +%\DescribeMacro{Exerightmargin} +%\DescribeMacro{Exelabelsep} +%The |ExerciseList| environment is nothing more than a |list| +%environment. All the parameters of \LaTeX's lists are +%available. Please consult your favourite source of information to have +%the exact definitions of these lengths. +% +%\begin{decl} +% \begin{tabular}{ll} +% |\QuestionBefore| & |\QuestionIndent| \\ +% |\subQuestionBefore| & |\subQuestionIndent| \\ +% |\subsubQuestionBefore| & |\subsubQuestionIndent| \\ +% \end{tabular} +%\end{decl} +%\DescribeMacro{QuestionBefore} +%\DescribeMacro{QuestionIndent} +%\DescribeMacro{subQuestionBefore} +%\DescribeMacro{subQuestionIndent} +%\DescribeMacro{subsubQuestionBefore} +%\DescribeMacro{subsubQuestionIndent} +%Here, |\QuestionBefore| is the vertical space above |\Question|, and\\ +%|\QuestionIndent| it the horizontal distance added to the margin in +%question. Same thing for |\subQuestion| and |\subsubQuestion|. +% +% \subsection{The \texttt{\textbackslash renewcounter} command} +% +%\changes{v1.1}{2004/09/05}{Added the 'renewcounter' command.} +% +% In a document, you will probably want to customise the way the +% |Exercise| counter will reseted. Strangely, it is impossible to +% redefined counter with \LaTeX. There is no equivalent of the +% |\renewcommand| command for the counters. +% +% We provide such an equivalent with the command |\renewcounter|. +%\DescribeMacro{\renewcounter} +% +%\begin{decl} +% |\newcounter|\marg{foo}\oarg{counter} +%\end{decl} +% The |\renewcounter| command defines a new counter named |foo|. The +% counter is initialized to zero. +% +% The optional argument \oarg{counter} causes the counter |foo| to be +% reset whenever the counter named in the optional argument is +% incremented. +% +% If the counter |foo| was not previously defined, an \LaTeX\ error +% occurs. +% +%\section{Known problems} +% +%The commands |\Question|, |\subQuestion|, etc. are heavily based +%on |list| environment. These lists are hidden (I know it's bad!) to +%simplify the syntax of the source file (I think it's nice!). +% +%In fact, every |\Question| is like the beginning of an environment, +%which is closed at the next |\Question| (the exact mechanism is a +%little bit more complicated). +% +%Consequently it's dangerous to put questions inside environment. +%The following code will lead to an error: +%\vspace*{-.5\baselineskip} +%\begin{verbatim} +% \begin{Exercise} +% \begin{multicols}{2} +% \Question ... +% \Question ... +% \end{multicols} +% \end{Exercise} +%\end{verbatim} +%Of course, you can put entire exercise inside other environment (like +%|minipage|).

So, +%this code will work: +%\vspace*{-.5\baselineskip} +%\begin{verbatim} +% \begin{Exercise} +% \begin{multicols}{2} +% \Question ... +% \Question ... +% \EndCurrentQuestion +% \end{multicols} +% \end{Exercise} +%\end{verbatim} +% +% +% +% +% +%In |ExerciseList| environment, the command |\Exercise| shouldn't be +%followed by an empty line. +% +% \PrintChanges +% +%\makeatletter\c@IndexColumns = 2\makeatother +% \StopEventually{\PrintIndex\newpage\tableofcontents } +% +% \section{Implementation} +% +% \subsection{Package options} +% This part deals with the package options.
