Matrix multiplication. Contains a function that will let you print the calculation steps of matrix multiplication, e.g. in the Advice.

Showing off the part types.

A demonstration of the exam-level variable override feature. The student is shown the same question several times, but each instance is set up to suggest a different error in the process of computing the median of a sample. The first instance is very easy, and the last is pretty hard.

A question designed to demonstrate the exam-level variable overrides feature. The student must work out the median of a given sample. The exam can override size of the sample, the range of numbers to pick, and whether the sample should be shown to the student in increasing order.

Demonstrates how to set up a "choose one from a list" part where the number of choices is randomised.

The part is given a list of labels for the choices as well as a list specifying the marks to award for each choice.

A short demonstration of when the basic simplification rules are turned on, or off.

Demo showing how to write a custom function in javascript.

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

This demonstrates how to render a set of tuples such as $\{(1,2),(3,4)\}$ in LaTeX, starting with a list of pairs of numbers.

Demonstrates how to create variables containing LaTeX commands, and how to use them in the question text.

Demonstrating that \$ produces a normal dollar sign.

Demonstrates that the marking algorithm for "match text pattern" parts doesn't put quotes around substituted strings any more.

A demo of the choose several from a list part and its options.

Demonstrates how to create variables containing LaTeX commands, and how to use them in the question text.

This question demonstrates defining an 'unknown' function $F(x)$ as a custom function so that it can be used in marking.

The definition of $F$ is arbitrary, so care must be taken to ensure it doesn't have more properties, such as evenness, than necessary.

A demo of the match text pattern part and its options.

A demonstration of how to use the "variable list of choices" option for a "choose one from a list" part to shuffle only some of the choices, and always have the same "I don't know" choice at the end of the list.

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.

Find a regression equation.

Now includes a graph of the regression line and another interactive graph gives users the opportunity to move the regression line around. Could be used for allowing users to experiment with what they think the line should be and see how this compares with the calculated line.

Also includes an updated SSE to see how the sum of the squares of the residuals varies with the regression line.
