\section{Introduction}

This is a sample file to give templates of the environments
defined in \texttt{exerquiz}. The file illustrates the
\texttt{exercise}, the \texttt{shortquiz} and \texttt{quiz}
environments.

In the case of the quiz environments, only multiple-choice
questions are illustrated. Open ended, or objective style
questions are demonstrated in other sample files.

\section{Online Exercises}

A well-designed sequences of exercises can be of aid to the student.  The
\texttt{exercise} environment makes it easy to produce electronic
exercises.  By using the \texttt{forpaper} option, you can also make a
paper version of your exercises. See the \texttt{aeb\_man.pdf} reference
manual.

\begin{exercise}
Evaluate the integral \(\displaystyle\int x^2 e^{2x}\,dx\).
\begin{solution}
We evaluate by \texttt{integration by parts}:\normalsize
\begin{alignat*}{2}
 \int x^2 e^{2x}\,dx &
   = \tfrac12 x^2 e^{2x} - \int x e^{2x}\,dx &&\quad
           \text{$u=x^2$, $dv=e^{2x}\,dx$}\\&
   = \tfrac12 x^2 e^{2x} -
           \Bigl[\tfrac12 x e^{2x}-\int \tfrac12 e^{2x}\,dx\Bigr] &&\quad
           \text{integration by parts}\\&
   = \tfrac12 x^2 e^{2x} - \tfrac12 x e^{2x} + \tfrac12\int e^{2x}\,dx &&\quad
           \text{$u=x^2$, $dv=e^{2x}\,dx$}\\&
   = \tfrac12 x^2 e^{2x} - \tfrac12 x e^{2x} + \tfrac14 e^{2x} &&\quad
           \text{integration by parts}\\&
   = \tfrac14(2x^2-2x+1)e^{2x} &&\quad
           \text{simplify!}
\end{alignat*}
\end{solution}
\end{exercise}

In the preamble of this document, we defined a \texttt{problem}
environment with its own counter.  Here is an example of it.

\begin{problem}
Is $F(t)=\sin(t)$ an antiderivative of $f(x)=\cos(x)$?  Explain
your reasoning.
\begin{solution}
The answer is yes. The definition states that $F$ is an
antiderivative of $f$ if $F'(x)=f(x)$.  Note that
$$
       F(t)=\sin(t) \implies F'(t) = \cos(t)
$$
hence, $F(x) = \cos(x) = f(x)$.
\end{solution}
\end{problem}

\begin{problem}
Is $F(t)=\sin(t)$ an antiderivative of $f(x)=\cos(x)$?  Explain
your reasoning.
\begin{solution}
The answer is yes. The definition states that $F$ is an
antiderivative of $f$ if $F'(x)=f(x)$.  Note that
$$
       F(t)=\sin(t) \implies F'(t) = \cos(t)
$$
hence, $F(x) = \cos(x) = f(x)$.
\end{solution}
\end{problem}

\noindent By modifying the \texttt{exercise} environment, you can
also create an \texttt{example} environment.  The one defined in
the preamble of this document has no associated counter.

\begin{example}
Give an example of a set that is \textit{clopen}.
\begin{solution}
The real number line is both closed and open in the usual topology of the
real line.%
\end{solution}
\end{example}

There is an \texttt{exercise*} environment, using it signals the presence
of a multiple part exercise question. The following exercise illustrates
this environment.

\begin{exercise*}\label{ex:parts}
Suppose a particle is moving along the $s$-axis, and that its position
at any time $t$ is given by $s=t^2 - 5t + 1$.
\begin{parts}
\item[h]\label{item:part} Find the velocity, $v$, of the particle at any time
$t$.
\begin{solution}
Velocity is the rate of change of position with respect to time. In
symbols:
$$
                    v = \frac{ds}{dt}
$$
For our problem, we have
$$
        v = \frac{ds}{dt} =\frac d{dt}(t^2 - 5t + 1) = 2t-5.
$$
The velocity at time $t$ is given by $\boxed{v=2t-5}$.
\end{solution}

\item Find the acceleration, $a$, of the particle at any time $t$.
\begin{solution}
Acceleration is the rate of change of velocity with respect to time.
Thus,
$$
                    a = \frac{dv}{dt}
$$
For our problem, we have
$$
        a = \frac{dv}{dt} =\frac d{dt}(2t-5)=2.
$$
The acceleration at time $t$ is constant: $\boxed{a=2}$.
\end{solution}
\end{parts}
\end{exercise*}

References can be made to a particular part of an exercise; for example,
``see \hyperref[item:part]{Exercise~\ref*{ex:parts}(\ref*{item:part})}.''
Part (a) is in \textcolor{webblue}{blue}; the solutions for that part is
``hidden''.  This is a new option for the \texttt{exercise} environment.

There is now an option for listing multi-part question in tabular form.
This problem style does not obey the \texttt{solutions\-after} option.

\begin{exercise*}
Simplify each of the following expressions in the complex number
system. \textit{Note}: $\bar z$ is the conjugate of $z$;
$\operatorname{Re} z$ is the real part of $z$ and
$\operatorname{Im} z$ is the imaginary part of $z$.
\begin{parts}[2]
\item $i^2$
\begin{solution}[]
$i^2 = -1$
\end{solution}
&
\item $i^3$
\begin{solution}[]
$i^3 = i i^2 = -i$
\end{solution}
\\
\item $z+\bar z$
\begin{solution}[]
$z+\bar z=\operatorname{Re} z$
\end{solution}
&
\item[h] $1/z$
\begin{solution}[]
$\displaystyle\frac 1z=\frac 1z\frac{\bar z}{\bar z}=\frac z{z\bar z}=\frac z{|z|^2}$
\end{solution}
\end{parts}
\end{exercise*}

\section{Short Quizzes with or without Solutions}


Short quizzes are quizzes with immediate response. As soon as the
user enters an answer, that answer is immediately evaluated, the
results of the evaluation are communicated to the user.

Solutions can optionally be included in each question. Below is a
\texttt{shortquiz} without solution.

\begin{shortquiz}
Was it in Xanadu did Kubla Kahn a stately pleasure dome
decree?
\begin{answers}{4}
\bChoices
    \Ans1 True\eAns
    \Ans0 False\eAns
\eChoices
\end{answers}
\end{shortquiz}

\noindent Below is a \texttt{shortquiz} with a solution.

\goodbreak

\begin{shortquiz*}[KublaKhan]
In what year did Columbus sail the ocean blue?
\begin{answers}[qzcolumbus1]{4}
\bChoices
    \Ans0 1490\eAns
    \Ans0 1491\eAns
    \Ans1 1492\eAns
    \Ans0 1493\eAns
\eChoices
\end{answers}
\begin{solution}
\begin{quote}
  In 1492, \\
  Columbus sailed the ocean blue.\hfill

  Profound was the logic in his quest,\\
  to get to the east, he headed west.\footnote{This poem was obtained by personal
  communication from Leonard A. Stefanski,
Department of Statistics, North Carolina State University.}
\end{quote}
\end{solution}
\end{shortquiz*}

\noindent These two types can be bundled together using the
\texttt{questions} environment.

\begin{shortquiz}
Answer each of the following. Passing is 100\%.

\begin{questions}

\item Was it in Xanadu did Kubla Kahn a stately pleasure dome
decree?
\begin{answers}{4}
\Ans1 True & \Ans0 False \\
\end{answers}

\item In what year did Columbus sail the ocean blue?
\begin{answers}[qzcolumbus2]{4}
\Ans0 1490 &\Ans0 1491 &\Ans1 1492 &\Ans0 1493
\end{answers}
\begin{solution}
\begin{quote}
  In 1492, \\
  Columbus sailed the ocean blue.

  Profound was the logic in his quest,\\
  to get to the east, he headed west.\footnote{This poem was obtained by personal
  communication from Leonard A. Stefanski,
Department of Statistics, North Carolina State University.}
\end{quote}
\end{solution}
\end{questions}
\end{shortquiz}

\noindent Try using the \texttt{proofing} option of \textsf{exerquiz}. In
this case, the correct answer is indicated to the side; useful, perhaps,
for proof-reading the document


\section{Graded Quizzes with JavaScript}

\CorrectionsOff % Don't want corrections for these two quizzes.

You can create graded quizzes using the \texttt{quiz} environment.
Here is a graded quiz using simple links.  This might be suitable for a
limited number of questions.

\begin{quiz}{qzdiscr1} Using the discriminant, $b^2-4ac$, respond to each of the
following questions.

\begin{questions}
\item Is the quadratic polynomial $x^2-4x + 3$ irreducible?
\begin{answers}{4}
\Ans0 Yes & \Ans1 No
\end{answers}
\item Is the quadratic polynomial $2x^2 - 4x + 3 $ irreducible?
\begin{answers}{4}
\Ans1 Yes &\Ans0 No
\end{answers}
\item How many solutions does the equation $2x^2 - 3x - 2= 0$ have?
\begin{answers}{4}
\Ans0 none &\Ans0 one &\Ans1 two
\end{answers}
\end{questions}
\end{quiz}\qquad\ScoreField{qzdiscr1}

\noindent By  using the \texttt*-option, you can create a multiple choice
set of question using check boxes.

\begin{quiz*}{qzdiscr2}
Using the discriminant, $b^2-4ac$, respond to each of the
following questions.

\begin{questions}
\item Is the quadratic polynomial $x^2-4x + 3$ irreducible?
\begin{answers}{4}

\item How many solutions does the equation $2x^2 - 3x - 2= 0$ have?
\begin{answers}{4}
\Ans0 none &\Ans0 one &\Ans1 two
\end{answers}
\end{questions}
\end{quiz*}\quad\ScoreField\currQuiz

\noindent The \texttt{proofing} option of \textsf{exerquiz} can be used to
mark the correct answer to the side; useful, perhaps, for proof-reading
the document


\section{Correcting Quizzes with JavaScript}\label{s:corrections}

\CorrectionsOn  % Now we want corrections

Beginning with version 1.2 of \textsf{exerquiz}, you can now grade
the quizzes created by the \texttt{quiz} environment.
In this section, we illustrate the \texttt{quiz} environment with
corrections.

There are two types: link-style and form-style.
This is the link-style format:


\begin{quiz}{qzTeXl} Answer each of the following. Passing
is 100\%.
\begin{questions}
\item Who created \TeX?
\begin{answers}4
\Ans1 Knuth &\Ans0 Lamport &\Ans0 Carlisle &\Ans0 Rahtz
\end{answers}
\item Who originally wrote \LaTeX?
\begin{answers}{4}
\Ans0 Knuth &\Ans1 Lamport &\Ans0 Carlisle &\Ans0 Rahtz
\end{answers}
\end{questions}
\end{quiz}\quad\ScoreField\currQuiz\CorrButton\currQuiz

\medskip
We can obtain the forms-style quiz simply by inserting an \texttt*
before the quiz field name.
\textcolor{red}{Important!}  Be sure to name each quiz field
differently!
