These original solutions cover all three questions, all nine lettered parts and all twenty-one answer units, including every optional question. Each question carries 25 marks; the examination counted the best two answers. The <local truncation error> in Question 3(a) is divided by the <step size>. In Question 3(c), the leading <coefficient> of a genuine $k$-step <linear multistep method> is understood to be nonzero.
