1. Look at the top left hand side of the 2nd page. angle between two lines formula is 'apparently' m1 + m2 / 1 - m1m2 --> I would be willing to bet my left nut that the formula is tanA = m1 - m2/ 1+m1m2

Also if you look at the solution for Q2 d(ii) the exponential decay question --- the solutions stops halfway, after calculating the value of k -- however that was only part of the process for finding the answer, what I mean to say is -- it doesn't provide the answer to the question -- those are the only two problem's I've found but I haven't looked at the solutions past Q3.

EDIT: Found another one, apparently 11-3 = 9... good lord
