    So what I've done is, I've found the value of M using the quadratic formula, this is in terms of S. Is this all I have to do? It feels inadequate...not that I'm undermining your way of thinking... I probably stopped short... so if i directly integrate M'= -M^2 + SM + I, which will presumably...

    Area of a parallelogram using determinants

    technically there is a 3rd vector which could be r = (0,0,0) and NEVER ignore any component given in a question like this :P So, let the origin = r therefore find the vectors rv and ru Then, find the magnitude of the cross product of the two vectors, rv and ru i.e. |rv x ru| Your answer...
