The questions are on Moodle and only accessible if you are enrolled in the course. Here are screenshots of some of them with a description of what is random.
Note that random questions the main challenge is that the results make sense. That is, it is better to randomly generate the result and work backwards from there.
In the question below I draw a random integer N and set N^2 inside the square root.
In the question below the offsets of the graph are random, i.e. the limits will be some random integer.
In the question below I generate a random function in the background and sample it at fixed points
In the question below I randomly decide whether its true or not and then also randomly pick a parametrized exponential function. If it is false I plot minus times the derivative.
In the question below the parts of the row echelon form that are nonzero and not a pivot are random. I then generate some random elementary transformation matrices to make the matrix shown to the students.
Here I draw random integer prices and then compute a budget such that the optimal k and w will be integers.
