SPM Mathematics 2018, Paper 2 (Questions 1 & 2)


Question 1 (3 marks):
(a) It is given that set E = {perfect square numbers} and set F = {9, 16, 25}.
Complete the Venn diagram in the answer space to show the relationship between set E and set F.

Answer:


(b)
 The Venn diagram in Diagram 1 shows the sets X, set Y and set Z.
The universal set, ξ = X U Y U Z.

Diagram 1

State the relationship represented by the shaded region between sets X, set Y and set Z.



Solution:

(a)


(b)


Hence, relationship represented by the shaded region between sets X, set Y and set are (X ∩ Y) ∪ Z.



Question 2 (3 marks):
Diagram 2 shows a cuboid PQRSTUVW on a horizontal plane. Point N is the midpoint of QR.
Diagram 2

(a)
Name the angle between the plane TWN and the plane PQRS.
(b) Calculate the angle between the plane TWN and the plane PQRS.


Solution:
(a)
Angle between the plane TWN and the plane PQRS
= ∠ WNR

(b)



tanWNR= 4 3 WNR= 53.13 o
