This package was designed with -mathematics problems in mind, but can be used for other subjects as well. The -idea is to create a file containing a large number of problems with their -solutions which can be read in by <span class="LATEX">L<span class="A">A</span><span class="TEX">T<span -class="E">E</span>X</span></span>, and then select a number of -problems to typeset. This means that once the database has been set up, -each year you can easily create a new problem sheet that is sufficiently -different from the previous year, thus preventing the temptation of current -students seeking out the previous year’s students, and checking out their -answers. There is also an option that can be passed to the package -to determine whether or not the solutions should be printed. In this -way, one file can either produce the student’s version or the teacher’s -version. -</p><!--l. 56--><p class="noindent" > -</p> -<!--l. 56--><p class="noindent" ><a -href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">2 </span> <a - id="x1-30002"></a>Package Options</h3> -<!--l. 57--><p class="noindent" >The following options may be passed to this package: - </p><dl class="description"><dt class="description"> -<span -class="ec-lmssbx-10x-x-109">answers</span><a - id="dx1-3001"></a> </dt><dd -class="description">Show the answers - </dd><dt class="description"> -<span -class="ec-lmssbx-10x-x-109">noanswers</span><a - id="dx1-3002"></a> </dt><dd -class="description">Don’t show the answers (default) - </dd><dt class="description"> -<span -class="ec-lmssbx-10x-x-109">draft</span><a - id="dx1-3003"></a> </dt><dd -class="description">Display the label and dataset name when a problem is used - </dd><dt class="description"> -<span -class="ec-lmssbx-10x-x-109">final</span><a - id="dx1-3004"></a> </dt><dd -class="description">Don’t display label and dataset name when a problem is used - </dd><dt class="description"> -<span -class="ec-lmssbx-10x-x-109">usedefaultargs</span><a - id="dx1-3005"></a> </dt><dd -class="description">Make <span -class="ec-lmtt-10x-x-109">\thisproblem</span><a - id="dx1-3006"></a> use the default arguments supplied in - the problem definition. - - - </dd><dt class="description"> -<span -class="ec-lmssbx-10x-x-109">nousedefaultargs</span><a - id="dx1-3007"></a> </dt><dd -class="description">Make <span -class="ec-lmtt-10x-x-109">\thisproblem</span><a - id="dx1-3008"></a> prompt for problem arguments - (default).</dd></dl> -<!--l. 69--><p class="noindent" > -</p> -<!--l. 69--><p class="noindent" ><a -href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">3 </span> <a - id="x1-40003"></a>Verbatim</h3> -<!--l. 71--><p class="noindent" >As from version 3.02, problems and solutions may contain verbatim text, but -you must use the <a - id="dx1-4001"></a><span -class="ec-lmtt-10x-x-109">fragile </span>(or <span -class="ec-lmtt-10x-x-109">fragile=true</span>) option for the associated -environments. -</p><!--l. 75--><p class="indent" > Alternatively, if most of your problems contain verbatim, you can globally set -this option using: - - -</p> - <div class="verbatim" id="verbatim-1"> -\setkeys{probsoln}{fragile} -</div> -<!--l. 79--><p class="nopar" > You can switch off this option using <span -class="ec-lmtt-10x-x-109">fragile=false</span>. -</p><!--l. 82--><p class="indent" > The <span -class="ec-lmtt-10x-x-109">fragile </span>option writes information to a temporary file.

United Kingdom.\\ -\url{http://theoval.cmp.uea.ac.uk/~nlct/}} - - \date{2012-08-23} - \maketitle -\tableofcontents - - \section{Introduction} -The \styfmt{probsoln} package is designed for teachers or lecturers -who want to create problem sheets for their students. This package -was designed with mathematics problems in mind, but can be used for -other subjects as well. The idea is to create a file containing a -large number of problems with their solutions which can be read in -by \LaTeX, and then select a number of problems to typeset. This -means that once the database has been set up, each year you can -easily create a new problem sheet that is sufficiently different -from the previous year, thus preventing the temptation of current -students seeking out the previous year's students, and checking out -their answers. There is also an option that can be passed to the -package to determine whether or not the solutions should be printed. -In this way, one file can either produce the student's version or -the teacher's version. - -\section{Package Options}\label{sec:pkgopt} -The following options may be passed to this package: -\begin{description} -\item[\pkgopt{answers}] Show the answers -\item[\pkgopt{noanswers}] Don't show the answers (default) -\item[\pkgopt{draft}] Display the label and dataset name when a problem is used -\item[\pkgopt{final}] Don't display label and dataset name when a problem is used -\item[\pkgopt{usedefaultargs}] Make \ics{thisproblem} use the -default arguments supplied in the problem definition. -\item[\pkgopt{nousedefaultargs}] Make \ics{thisproblem} prompt for -problem arguments (default). -\end{description} - -\section{Verbatim}\label{sec:verbatim} - -As from version 3.02, problems and solutions may contain verbatim -text, but you must use the \iterm{fragile}\texttt{fragile} (or -\texttt{fragile=true}) option for the associated environments. - -Alternatively, if most of your problems contain verbatim, you can -globally set this option using: -\begin{verbatim} -\setkeys{probsoln}{fragile} -\end{verbatim} -You can switch off this option using \texttt{fragile=false}. - -The \texttt{fragile} option writes information to a temporary file. -This defaults to "\jobname.vrb" but the name may be changed. The -extension (".vrb") is given by: -\begin{definition}[\DescribeMacro{\ProbSolnFragileExt}] -\cs{ProbSolnFragileExt} -\end{definition} -The base name (\cs{jobname}) is given by: -\begin{definition}[\DescribeMacro{\ProbSolnFragileFile}] -\cs{ProbSolnFragileFile} -\end{definition} - -\section{Showing and Hiding Solutions}\label{sec:showanswers} - -In addition to the \pkgopt{answers} and \pkgopt{noanswers} package -options, it is also possible to show or suppress the solutions -using -\begin{definition}[\DescribeMacro{\showanswers}] -\cs{showanswers} -\end{definition} -and -\begin{definition}[\DescribeMacro{\hideanswers}] -\cs{hideanswers} -\end{definition} -respectively. - -The boolean variable \bool{showanswers} determines whether the -answers should be displayed. You can use this value with the -\sty{ifthen} package to specify different text depending on -whether the solutions should be displayed. For example: -\begin{verbatim} -Assignment 1\ifthenelse{\boolean{showanswers}}{ (Solution Sheet)}{} -\end{verbatim} -Alternatively you can use \ics{ifshowanswers}\ldots\cs{else}\ldots -\cs{fi}: -\begin{verbatim} -Assignment 1\ifshowanswers\space (Solution Sheet)\fi -\end{verbatim} - -For longer passages, you can use the environments -\begin{definition}[\DescribeEnv{onlyproblem}] -\cs{begin}\marg{onlyproblem}\oarg{option} -\end{definition} -and -\begin{definition}[\DescribeEnv{onlysolution}] -\cs{begin}\marg{onlysolution}\oarg{option} -\end{definition} -For example: -\begin{verbatim} -\begin{onlyproblem}% -What is the derivative of $f(x) = x^2$? -\end{onlyproblem}% -\begin{onlysolution}% -$f'(x) = 2x$ -\end{onlysolution} -\end{verbatim} -The above will only display the question if \bool{showanswers} -is false and will only display the solution if \bool{showanswers} -is true. If you want the question to appear in the answer -sheet as well as the solution, then don't put the question in -the \env{onlyproblem} environment: -\begin{verbatim} -What is the derivative of $f(x) = x^2$? -\begin{onlysolution}% -Solution: $f'(x) = 2x$ -\end{onlysolution} -\end{verbatim} - -\begin{important} -If you want to include verbatim text in the body of -\env{onlyproblem} or \env{onlysolution}, you need to specify -\texttt{fragile} in the optional argument of the environment. -(See \sectionref{sec:verbatim} for further details.) -\end{important} - -If you use \envfmt{onlysolution} within the \env{defproblem} -environment, the problem will be tagged as having a solution -and will be added to the list used by \ics{foreachsolution}. -The optional argument of \envfmt{onlysolution} (and \env{onlyproblem}) -is inherited from the parent \env{defproblem} setting. - -\section{General Formatting Commands}\label{sec:formatting} - -The commands and environments described in this section are -provided to assist formatting problems and their solutions. -\begin{definition}[\DescribeEnv{solution}] -\verb|\begin{solution}|\meta{text}\verb|\end{solution}| -\end{definition} -By default, this is equivalent to -\begin{display} -\verb|\par\noindent\textbf{\solutionname}: |\meta{text} -\end{display} -where \DescribeMacro{\solutionname}\cs{solutionname} defaults -to \dq{\solutionname}. Note that you must place the \env{solution} -environment inside the \envfmt{onlysolution} environment or -between \ics{ifshowanswers}\ldots\cs{fi} to ensure that it -is suppressed when the solutions are not wanted. (See -\sectionref{sec:showanswers}.) - - -Note that the \styfmt{probsoln} package will only define the -\env{solution} environment if it is not already defined. - -\begin{definition}[\DescribeEnv{textenum}] -\verb|\begin{textenum}|\ldots\verb|\end{textenum}| -\end{definition} -The \envfmt{textenum} environment is like the \env{enumerate} -environment but is in-line. It uses the same counter that the -\envfmt{enumerate} environment would use at that level so the -question can be compact but the answer can use \envfmt{enumerate} -instead. For example: -\begin{verbatim} -\begin{onlyproblem}% - Differentiate the following: - \begin{textenum} - \item $f(x)=2^x$; \item $f(x)=\cot(x)$ - \end{textenum} -\end{onlyproblem} -\begin{onlysolution} - \begin{enumerate} - \item - \begin{align*} - f(x) &= 2^x = \exp(\ln(x^2)) =\exp(2\ln(x))\\ - f'(x) &= \exp(2\ln(x))\times \frac{2}{x}\\ - &= f(x)\frac{2}{x} - \end{align*} - \item - \begin{align*} - f(x) &= \cot(x) = (\tan(x))^{-2}\\ - f'(x) &= -(\tan(x))^{-2}\times\sec^2(x)\\ - &=-\csc^2x - \end{align*} - \end{enumerate} -\end{onlysolution} -\end{verbatim} -In this example, the items in the question are brief, so an -\env{enumerate} environment would result in a lot of unnecessary -white space, but the answers require more space, so an -\envfmt{enumerate} environment is more appropriate. Since the -\envfmt{textenum} environment uses the same counters as the -\envfmt{enumerate} environment, the question and answer sheets use -consistent labelling. Note that there are other packages available -on CTAN that you can use to create in-line lists. Check the -\urlfootref{http://www.tex.ac.uk/tex-archive/help/Catalogue/bytopic.html\#enumeration}{TeX -Catalogue} for further details. - -\DescribeMacro{\correctitem}\DescribeMacro{\incorrectitem} -\begin{definition} -\cs{correctitem}\\ -\cs{incorrectitem} -\end{definition} -You can use the commands \cs{correctitem} and \cs{incorrectitem} -in place of \ics{item}. If the solutions are suppressed, these -commands behave in the same way as \cs{item}, otherwise they -format the item label using one of the commands: -\DescribeMacro{\correctitemformat}\DescribeMacro{\incorrectitemformat} -\begin{definition} -\cs{correctitemformat}\marg{label}\\ -\cs{incorrectitemformat}\marg{label} -\end{definition} -For example: -\begin{verbatim} -Under which of the following functions does $S=\{a_1,a_2\}$ -become a probability space? -\begin{enumerate} -\incorrectitem $P(a_1)=\frac{1}{3}$, $P(a_2)=\frac{1}{2}$ -\correctitem $P(a_1)=\frac{3}{4}$, $P(a_2)=\frac{1}{4}$ -\correctitem $P(a_1)=1$, $P(a_2)=0$ -\incorrectitem $P(a_1)=\frac{5}{4}$, $P(a_2)=-\frac{1}{4}$ -\end{enumerate} -\end{verbatim} -The default definition of \cs{correctitemformat} puts a frame around -the label. - -\section{Defining a Problem}\label{sec:defproblem} - -It is possible to construct a problem sheet with solutions using the -commands described in the previous sections, however it is also -possible to define a set of problems for later use. In this way you -can create an external file containing many problems some or all of -which can be loaded and used in a document. The \styfmt{probsoln} -package has a default data set labelled \dq{default} in which you -can store problems. Alternatively, you can create multiple data -sets. You can then iterate through each problem in a problem set. -You can use a previously defined problem more than once, which means -that by judicious use of \env{onlyproblem}, \env{onlysolution} or -the \bool{showanswers} boolean variable in conjunction with -\ics{showanswers} and \ics{hideanswers}, you can print the solutions -in a different location to the questions (for example in an -appendix). - -\begin{definition}[\DescribeEnv{defproblem}] -\verb|\begin{defproblem}|\oarg{n}\oarg{default args}\marg{label}\oarg{option}\newline -\meta{definition}\newline -\verb|\end{defproblem}| -\end{definition} -This defines the problem whose label is given by \meta{label}. The -label must be unique for a given data set and should not contain -active characters or a comma. (Active characters include the special characters -such as \$ and \&, but some packages may make other symbols active, -such as the colon (:) character. For example, the \sty{ngerman} and -\sty{babel} packages make certain punctuation active. Check the -relevant package documentation for details.) - -\begin{important} -The final optional argument \meta{option} may be \texttt{fragile} to -indicate that the problem contains verbatim text. Any occurrences of -\env{onlyproblem} or \env{onlysolution} contained within -\envfmt{defproblem} are inherited from \envfmt{defproblem}. (See -\sectionref{sec:verbatim} for further details.) -\end{important} - -If \env{defproblem} occurs in the document or is included via -\ics{input} or \ics{include}, then the problem will be added to -the default data set. If \envfmt{defproblem} occurs in an external -file that is loaded using one of the commands defined in -\sectionref{sec:load} then the problem will be added to -the specified data set. - -The contents of the \env{defproblem} environment should be the text -that defines the problem. This may include any of the commands -defined in \sectionref{sec:showanswers} and -\sectionref{sec:formatting}. - -The problem may optionally take \meta{n} arguments (where -\meta{n} is from 0 to 9). The arguments can be referenced -in the definition via \texttt{\#1},\ldots,\texttt{\#9}. -If \meta{n} is omitted then the problem doesn't take any -arguments. -The following example defines a problem with one argument: -\begin{verbatim} -\begin{defproblem}[1]{diffsin} -Differentiate $f(x)=\sin(#1x)$. -\begin{onlysolution}% - \begin{solution} - $f'(x) = #1\cos(#1x)$ - \end{solution} -\end{onlysolution} -\end{defproblem} -\end{verbatim} - -The second optional argument \meta{default args} supplies -default problem arguments that will automatically be used within -\ics{thisproblem} when used in \ics{foreachproblem} in conjunction -with the package option \pkgopt{usedefaultargs}. (See \sectionref{sec:foreach}.) -For example: -\begin{verbatim} -\begin{defproblem}[1][{2}]{diffsin} -Differentiate $f(x)=\sin(#1x)$. -\begin{onlysolution}% - \begin{solution} - $f'(x) = #1\cos(#1x)$ - \end{solution} -\end{onlysolution} -\end{defproblem} -\end{verbatim} - -\begin{definition}[\DescribeMacro{\newproblem}] -\cs{newproblem}\oarg{n}\oarg{default args}\marg{label}\marg{problem}\marg{solution} -\end{definition} -This is a shortcut command for: -\begin{ttfamily}\obeylines -\cs{begin}\{defproblem\}\oarg{n}\oarg{default args}\marg{label}\% -\meta{problem}\% -\cs{begin}\{onlysolution\}\% -\cs{begin}\{solution\}\% -\meta{solution}\% -\cs{end}\{solution\}\% -\cs{end}\{onlysolution\}\% -\cs{end}\{defproblem\} -\end{ttfamily} -For example: -\begin{verbatim} -\newproblem[1]{diffsin}{% - \(f(x) = \sin(#1x)\) -}% -{% - \(f'(x) = #1\cos(#1x)\) -} -\end{verbatim} -is equivalent to -\begin{verbatim} -\begin{defproblem}[1]{diffcos}% - \(f(x) = \cos(#1x)\) -\begin{onlysolution}% - \begin{solution}% - \(f'(x) = -#1\sin(#1x)\) - \end{solution}% -\end{onlysolution}% -\end{defproblem} -\end{verbatim} -(In this example, the argument will need to be a positive number -to avoid a double minus in the answer. If you want to perform -floating point arithmetic on the arguments, then try the -\sty{fp} or \sty{pgfmath} packages.) - -Alternatively, if you want to supply default arguments to use when -iterating through problems with \ics{foreachproblem}: -\begin{verbatim} -\newproblem[1][{3}]{diffsin}{% - \(f(x) = \sin(#1x)\) -}% -{% - \(f'(x) = #1\cos(#1x)\) -} -\end{verbatim} - - -\begin{definition}[\DescribeMacro{\newproblem*}] -\cs{newproblem*}\oarg{n}\oarg{default args}\marg{label}\marg{definition} -\end{definition} -This is a shortcut for: -\begin{ttfamily}\obeylines -\cs{begin}\{defproblem\}\oarg{n}\oarg{default args}\marg{label}\% -\meta{definition}\% -\cs{end}\{defproblem\} -\end{ttfamily} - -\begin{important} -Note that you can't use verbatim text with \cs{newproblem} or -\cs{newproblem*}. Use the \env{defproblem} environment instead with -the \texttt{fragile option}. -\end{important} - -\section{Using a Problem}\label{sec:useproblem} - -Once you have defined a problem using \env{defproblem} or -\ics{newproblem} (see \sectionref{sec:defproblem}), you can -later display the problem using: -\begin{definition}[\DescribeMacro{\useproblem}] -\cs{useproblem}\oarg{data set}\marg{label}\marg{arg$_1$}\ldots -\marg{arg$_N$} -\end{definition} -where \meta{data set} is the name of the data set that contains -the problem (the default data set is used if omitted), -\meta{label} is the label identifying the required problem and -\meta{arg$_1$}, \ldots, \meta{arg$_N$} -are the arguments to pass to the problem, if the problem was -defined to have arguments (where $N$ is the number -of arguments specified when the problem was defined). - -For example, in the previous section the problem \texttt{diffcos} -was defined to have one argument, so it can be used as follows: -\begin{verbatim} -\useproblem{diffcos}{3} -\end{verbatim} -This will be equivalent to: -\begin{verbatim} -\(f(x) = \cos(3x)\) -\begin{onlysolution}% -\begin{solution}% -\(f'(x) = -3\sin(3x)\) -\end{solution}% -\end{onlysolution}% -\end{verbatim} - -\section{Loading Problems From External Files}\label{sec:load} - -You can store all your problem definitions (see -\sectionref{sec:defproblem}) in an external file. -These problems can all be appended to the default data set by -including the file via \ics{input} or they can be appended -to other data sets using one of the commands described below. -Once you have loaded all the required problems, you can -iterate through the data sets using the commands described -in \sectionref{sec:foreach}. Note that the commands below -will create a new data set, if the named data set doesn't -exist. - -\begin{definition}[\DescribeMacro{\loadallproblems}] -\cs{loadallproblems}\oarg{data set}\marg{filename} -\end{definition} -This will load all problems defined in \meta{filename} and -append them to the specified data set, in the order in which -they are defined in the file. If \meta{data set} is -omitted, the default data set will be used. If \meta{data set} -doesn't exist, it will be created. - -\begin{definition}[\DescribeMacro{\loadselectedproblems}] -\cs{loadselectedproblems}\oarg{data set}\marg{labels}\marg{filename} -\end{definition} -This is like \cs{loadallproblems}, but only those problems whose -label is listed in the comma-separated list \meta{labels} are -loaded. For example, if I have some problems defined in the -file \texttt{derivatives.tex}, then -\begin{verbatim} -\loadselectedproblems{diffsin,diffcos}{derivatives} -\end{verbatim} -will only load the problems whose labels are \texttt{diffsin} -and \texttt{diffcos}, respectively. All the other problems in -the file will remain undefined. - -\begin{definition}[\DescribeMacro{\loadexceptproblems}] -\cs{loadexceptproblems}\oarg{data set}\marg{exception list}\marg{filename} -\end{definition} -This is the reverse of \cs{loadselectedproblems}. This loads all -problems except those whose labels are listed in \meta{exception -list}. - -\begin{definition}[\DescribeMacro{\loadrandomproblems}] -\cs{loadrandomproblems}\oarg{data set}\marg{n}\marg{filename} -\end{definition} -This randomly loads \meta{n} problems from \meta{filename} and -adds them to the given data set. If \meta{data set} is omitted, -the default data set is assumed. Note that the problems will be -added to the data set in a random order, not in the order in -which they were defined.

As from version 3.03, you can now do -this. - -The \sty{probsoln} package defaults to the UK academic year, which -starts in September. If this isn't appropriate, you can change it -using: -\begin{definition}[\DescribeMacro{\SetStartMonth}] -\cs{SetStartMonth}\marg{n} -\end{definition} -where \meta{n} is the number of the month. (1 = January, 2 = -February, etc.) - -The \emph{start year} is the calender year in effect when the -academic year started. For example, if this is the academic year -2011/12, then the start year is 2011. This is automatically set to -the start of the current academic year. It is also updated when -\cs{SetStartMonth} is used.\footnote{So don't use \cs{SetStartMonth} -after \cs{SetStartYear}.} If you want to set it to a specific year, -you can use: -\begin{definition}[\DescribeMacro{\SetStartYear}] -\cs{SetStartYear}\marg{year} -\end{definition} -For example: \verb|\SetStartYear{2008}| indicates the academic year -2008/9. - -There are two files concerned with previously used labels. They are: -\begin{description} - - \item[The previously used labels file] This keeps track of all - problems used in previous years, as well as problems used by - other documents that have this as their previously used labels - file, and it contains the problem labels from the last run of - the current document. - - \item[The current used labels file] This defaults to -\cs{jobname}\texttt{.prb}, but the name can be changed using: - \begin{definition}[\DescribeMacro{\SetUsedFileName}] - \cs{SetUsedFileName}\marg{name} - \end{definition} - This file keeps track of all the labels used in the current - document from the previous \LaTeX\ run. Note that if you want to - delete this file, first clear it using - \begin{definition}[\DescribeMacro{\ClearUsedFile}] - \cs{ClearUsedFile}\marg{file} - \end{definition} - in place of \cs{ExcludePreviousFile}\marg{file}, described below. - The argument \meta{file} is the previously used labels file - described above. \cs{ClearUsedFile} will remove all labels in - the current used labels file from the previously used labels file - and clear the current used labels file. Once this file is empty, - it may then be deleted. - -\end{description} - -Before loading randomly selected problems, first specify the -previously used labels file with the command: -\begin{definition}[\DescribeMacro{\ExcludePreviousFile}] -\cs{ExcludePreviousFile}\oarg{number of years}\marg{file name} -\end{definition} -where \meta{file name} is the name of the previously used file. The -optional argument \meta{number of years} specifies the year cut-off. -This defaults to 3, which means that only those labels used this -year or the previous 2 years will be kept. Any problems used before -then may be reused. - -Suppose I'm lecturing a first year undergraduate mathematics course -(designated, say, mth101).

If the problem requires arguments, -and no default arguments were supplied in the problem definition or -the package option \pkgopt{usedefaultargs} was not used, then -you will be prompted for arguments, so if you want to use this -approach you will need to use \LaTeX\ in interactive mode.
