The pattern match on line 10 of the custom function no longer appears to handle the commutativity of the expression, despite using the doCommute option. E.g. $2*(17x+2)$ is not acccepted, however $(17x+2)*2$ is.

Checkpointing before looking at the problem with the user defined function mark_factorised which no longer appears to be functioning correctly.

This is a rewrite of a question form the Newcastle University Biomechanics project, which seems more appropriate in the Transition to university project. The question originally used Geogebra to display he vectors; I've re-written in JSXGraph.
