  • Andrew's copy of Pattern matching - factorise an equation

    Question by Picture of Andrew Iskauskas Andrew Iskauskas

    The student is asked to factorise a quadratic $x^2 + ax + b$. 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.

  • Ben's copy of Displaying a randomised LaTeX command

    Question by Picture of Ben Brawn Ben Brawn

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

  • Block has friction (static or kinetic)

    Question by Tom Stallard

    A block of given mass is sits on a flat plane with defined static and kinetic friction values. Randomly, it does one of two things, it is either:

    1) pushed with enough force to start it moving - calculate the force on the block or the static friction.

    2) moving over a distance - calculate the work done or the kinetic friction

    (are these uneven calculations)
