INSTRUCTIONS
• Use black ink. You can use an HB pencil, but only for graphs and diagrams.
• Write your answer to each question in the space provided in the Printed Answer
Booklet. If you need extra space use the lined pages at the end of the Printed
Answer Booklet. The question numbers must be clearly shown.

1 In this question you must show detailed reasoning.
The number N is written as 28A3B in base-12 form.
Express N in decimal (base-10) form. [2]
2 The points A and B have position vectors a and b relative to the origin O. It is given that
J N KJ ON
K2 b m , where m is a real parameter.
aO =
KK 4 OO and = K-4O
K O
3
L mP L 6P
(a) In the case when m = 3, determine the area of triangle OAB. [4]
(b) Determine the value of m for which a # b = 0. [2]
3 The surface S has equation
z = f(x, y), where f(x, y) = 4x2y - 6xy2 - 1 12x4 for all real values of x
and y. You are given that S has a stationary point at the origin, O, and a second stationary point at
the point P(a, b, c), where c = f(a, b).
(a) Determine the values of a, b and c. [6]
(b) Throughout this part, take the values of a and b to be those found in part (a).
(i) Evaluate fx at the points U1 ^a - 0.1, b , f(a - 0.1, b)h and U2 ^a + 0.1, b , f(a + 0.1, b)h.
[2]
(ii) Evaluate fy at the points V1 ^a , b - 0.1, f (a, b - 0.1)h and V2 ^a , b + 0.1, f(a, b + 0.1)h.
[2]
(iii) Use the answers to parts (b)(i) and (b)(ii) to sketch the portions of the sections of S,
given by
• z = f(x, b), for x - a G 0.1,
• z = f (a, y), y - G 0.1. [2]
for b
4 The first five terms of the Fibonacci sequence, "Fn,, where n H 1, are
F1 = 1, F2 = 1, F3 = 2, F4 = 3 and F5 = 5.
(a) Use the recurrence definition of the Fibonacci sequence, Fn +1 = Fn + Fn -1 , to express
Fn +4 in terms of Fn and Fn - 1 . [2]
(b) Hence prove by induction that Fn is a multiple of 3 when n is a multiple of 4. [3]
