Ok, let me post up a few that had me puzzled:
3) ABC is a triangle and N is a point on AC
<ABn=<CBN=<BCN
BC=2a, CA=b, AB=c
BN=CN=d
i) Given that triangle ABN ||| triangle ACB, show that c^2 = b^2 - 2ac
ii) hence show that (a+c)^2 = a^2 + b^2
6ai) If W= inverse tan A + inverse tan B, show that tan W = A + B / 1 - AB
ii) hence solve the equation inverse tan 3x + inverse tan 2x = pi/4
And if anyone has the paper, question 7 (induction). Its a lot to type out.
