FAQ
Consider the case that the answer to a problem is an interval or an union of disjoint intervals.
The optional TeX command \allowIntervalUnionsForInput[true]
enables the option that the student's answer can be given by the union of multiple intervals.
The solution is defined by a left and a right boundary , both seperated by a semicolon.
symbol | |
---|---|
open left boundary | ( or ] |
closed left boundary | [ |
open right boundary | ) or [ |
closed right boundary | ] |
e.g. \solution{(-1;1]}
, \solution{]-1;1]}
(same interval as the first one), \solution{(myVar;100[}
The correct solution as an union of multiple disjoint intervals can be given by separating them with a comma. E.g. \solution{(-infinity;2],[3;infinity)}
Be aware that this is only possible if the optional command \allowIntervalUnionsForInput[true]
is used.
12345678910 \begin{question}
\text{Write down the interval from 1 to 3:}
\type{input.interval}
\begin{answer}
\text{ A = }
\solution{[1;3]}
\end{answer}
\end{question}
123456789 \begin{question}
\begin{answer}
\text{input.interval: $[1;4) = $}
\allowIntervalUnionsForInput
\solution{[1;4)}
\end{answer}
\end{question}
If you want that the solution and/or the answer boundaries can be written as multiple of π use the command \allowForInput{pi}
.
12345 \begin{answer}
\text{input.interval: $[\pi;4\cdot\pi) = $}
\allowForInput{pi}
\solution{[pi;4*pi)}
\end{answer}
