Really? You are mellowing! The 'weekly dates' thread has clearly had an effect on your life ;-)

I don't know if I would set it as homework either but it is just the sort of thing my 'programming' (matlab) teacher would set, although he also teaches maths here so that isn't too surprising. It's quite fun be 'taught' how to program by someone who has only ever done any in FORTRAN and C to model chemical systems (Plus some he did for the French military during his national service).
