This section explores the different types of exercises Ximera supports.
Basic Function Answer Type
The basic way of including a answerable item in Xiemra is to use the \answer command. The \answer must be inside of an environment.
\begin{question}
$3\times 2 = \answer{6}$
\end{question}
Will produce the question:
In addition to numerical answers, we also support elementary functions:
\begin{question}
$ \frac{\partial}{\partial x} x^2\sin(y) = \answer{2x\sin(y)}$
\end{question}
Produces:
Under the hood, Ximera is parsing the user input, producing a function, and
checking the user input function against “answer” at different complex
numbers, and seeing if the results are “reasonably” close to each other. We
compare the complex extensions of these functions to circumvent domain
issues.
While any environment can contain the command \answer, there are four special environments: question, exercise, problem, exploration. Each of these environments is the same, except for the name. These environment interact with the optional arguments in the documentclass in useful ways. We’ll discuss this later.
Choice Answer Type
Multiple Choice
\begin{question}
Which of the following functions has a graph which is a parabola?
\begin{multipleChoice}
\choice[correct]{$y=x^2+3x-3$}
\choice{$y = \frac{1}{x+2}$}
\choice{$y=3x+1$}
\end{multipleChoice}
\end{question}
Produces:
Select All
\begin{question}
Which of the following numbers are even?
\begin{selectAll}
\choice[correct]{$2$}
\choice{$1$}
\choice[correct]{$-4$}
\choice[correct]{$0$}
\end{selectAll}
\end{question}
