Answer all questions.
1. If A, B and C are arbitrary sets,:' show that [CA - B) n (A - C)] u B u C = Au B u C. [4]
2. Using the trapezium rule, with five ordinates, evaluate C .J1 + e dx, giving your answer correct to three decimal places.
3. The functions g and h are defined as follows: g:x-+x3'-1 , x>O; h:x-+5e-X, x>O
(a) Show that the composite function gh exists and define it in a similar form.
(b) Detennine the range of gh.

4. Determine the positive value of p if z = p - 3i and z is a real number. I-J)i
[4]
[5]
Hence, find the real number. [6]
5. Using the factor theorem, show that (3x + 1) is a factor of f(x), where f(x) =: 6x3 + 23x2 - 5x - 4. Hence, factorise f(x) completely. [4] Determine the range of x such that f(x) > O. [2]
6. Find
(a) J 2cosx dx, sin x + cosx
[Hints : You may use 2 cos x = (sin x + cos x) + (cos x - sin x)]
(b) Jln(2x) dx
7. Find the constants A, B, C, D' and E such that
4X4 +3x 2 -x-3 E A B Cx+D =: + -+-+-.,,---

8. (a) Expand (1 + 2X)3 up to and including the term in x3. Use your series to obtain a I
value for (1.04)3 giving five decimal places in your answer. [6]
(b) The first term of a geometric progression is 5, its last term is 640 and its sum is 1275. Find the common ratio. [4]
9. PQRS is a rhombus and tangent of the angle between PR and PQ is 3. Given that P(-I,O) and R(3, 8), find the coordinates ofthe points Q and S. [11]
10. (a) Find the equation of the asymptotes of the curve 2x-3
[lJ v=-----J (x-1)(x+3)
(b) Find the points where the curve intersects the x-axis and y-axis, and find the stationary points of the curve. [7]
(c) Sketch the curve.
(d) Determine the values of k for which the equation 2x - 3 = k(x - l)(x + 3)
has only one real root.
11. Show that the equation xex+1 = 4 has only one root and that this root lies in the
[3]
[1]
interval 0 < x < l. [6] Taking x = 0.6 as the initial value, apply the Newton-Raphson process to find this
root correct to three decimal places. [6] .
12. (a) Matrix M is given as
M~ l~~ ~1 ~ J Find the values of p, q and r such that M3 +pM2 + qM + rI = O.
