QP
Mathematics A
• a scientific or graphical calculator
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.

6 One of the regions bounded by two polar curves, C1 and C2 , is used to model the face of a flat
earring.
The polar equations of C1 and C2 are
C1: r = 2i
C2: r = i2
where 0 G i G r.
The curves C1 and C2 are shown in the diagram below with the region used to model the earring
shaded.
