Demo of automatically generating latex strings to out put vectors/matrices of variable size and that are calculated by some formula.

In this demo question, you can see either 2 or 3 gaps depending on the variable m, and the marking algorithm doesn't penalise for the empty third gap in cases when it is not shown.
Reason to use it: for vectors or matrices containing only numbers, one can easily use matrix entry to account for a random size of an answer. But this does not work for mathematical expressions. There we have to give each entry of the vector as a separate gap, which then becomes a problem when the size varies. This solves that problem. For this reason I've included two parts: one very simple one that just shows the phenomenon of variable number of gaps, and one which is more like why I needed it.
Note that to resolve the fact that when m=2, the point for the third gap cannot be earned, I have made it so that the student only gets 0 or all points, when all shown gaps are correctly filled in.
Note the use of Ax[m-1] in the third gap "correct answer" of part b): if you use Ax[2], then it will throw an error when m=2, as then Ax won't have the correct size. So even though the marking algorithm will ignore it, the question would still not work.
Bonus demo if you look in the variables: A way to automatically generate the correct latex code for [Math Processing Error][Math Processing Error], since it's a variable size. I would usually need that in the "Advice", i.e. solutions, rather than the question text.

Question in Simon's workspace
This question uses the GeoGebra extension so it can ask the student to create an equilateral triangle. It doesn't matter how they do it, as long as they end up with a polygon with three vertices whose sides are all the same length.

Demo question: do some sneaky symbolic differentiation to check that the student's answer is the integral of the expression they're given.
Needs an advice section before it can be used.

Experimental question using JSXGraph to provide dynamic, interactive graphs.
-
The student is asked to factorise a quadratic x2+ax+b. A custom marking script uses pattern matching to ensure that the student's answer is of the form (x+a)(x+b), (x+a)2, or x(x+a).
To find the script, look in the Scripts tab of part a.
