Question in Matrices
This question concerns the evaluation of the eigenvalues and corresponding eigenvectors of a 2x2 matrix.

Question in HowtosThe matrix entry part in this question marks any symmetric matrix as correct, using a custom marking algorithm. A matrix is symmetric if it is equal to its transpose.

Question in Demos
Ask the student to find a matrix corresponding to a given rotation about the origin.
Then ask them to find the determinant. Their answer is marked against the matrix they gave, not just the correct one.
Finally, ask them to find the inverse of their matrix. Marking is against the matrix and determinant they gave.

Question in Howtos
Demo question showing how to use the matrix maths functions in JavaScript.

Question in Howtos
This question adds a CSS rule to hide the brackets around the matrix input.

Question in Howtos
Some custom CSS restyles the matrix input so it looks like a fraction, with input boxes on top and bottom.
Ideally, there should be a fraction input part type, or an option for the number entry part to display a fraction input.

Question in Howtos
A randomly generated list of numbers is shown to the student. They must tick every occurrence of the lowest number. The number of occurrences isn't always the same  sometimes the minimum is unique and sometimes it is repeated. The
map
function makes it easy to construct a marking matrix. 
Question in Howtos
The student has to compute $a^b$ and $b^a$, then decide which of the two is bigger.
This question shows how to set up a custom marking matrix for the "choose one from a list" part, based on values used elsewhere in the question. It could use adaptive marking to use the student's incorrect values for the comparison, but doesn't at the moment.

Question in HowtosThis question shows how to make the correct answer to a "choose one from a list" part depend on randomised question variables, in a couple of ways. The first part uses JME expressions to define the marks available for each choice. The second part uses the "custom marking matrix" option.
