M is for Murder – Oh, No, someone's already done that one

Quick revision of the main M1 ideas – and some of the solutions to past papers. Quality of reproduction is not brilliant so apologies for that.
As always be wary of just skimming the solutions without following through with some serious thinking – and especially be careful of the mischievous minus sign and negative number error! If you find one please let me know.

MEI M2 follows on from OCR M1 fairly reasonably, so there is hardly any overlap.

Seriously – Mechanics can be quite challenging as applied maths courses go, unless you do lots of developmental study which will enable you to understand some of the vocabulary and contexts which appear in exams (and real life).
