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.

boundary | symbol |
---|---|

open left | `(` or `]` |

closed left | `[` |

open right | `)` or `[` |

closed right | `]` |

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.

12345 `\begin{answer}`

` `

`\type{input.interval}`

` `

`\text{Write down the interval from 1 to 3:}`

` `

`\solution{[1;3]}`

`\end{answer}`

123456 `\begin{answer}`

` `

`\type{input.interval}`

` `

`\text{input.interval: $[1;4) = $}`

` `

`\allowIntervalUnionsForInput`

` `

`\solution{[1;4)}`

`\end{answer}`

If you want that the solution and/or the answer boundaries can be written as multiple of π use the command `\allowForInput{pi}`

.

123456 `\begin{answer}`

` `

`\type{input.interval}`

` `

`\text{input.interval: $[\pi;4\cdot\pi) = $}`

` `

`\allowForInput{pi}`

` `

`\solution{[pi;4*pi)}`

`\end{answer}`
