(a) Copy and complete the table of values, correct to one decimal place, for the relation \(y = 3\sin x + 2\cos x\) for \(0° \leq x \leq 360°\).

x 30° 60° 90° 120° 150° 180° 210° 240° 270° 300° 330° 360°
y       3.0 1.6   -2.0   -3.6 -3.0     2.0

(b) Using scales of 2cm to 30°mon the x- axis and 2cm to 1 unit on the y- axis, draw the graph of the relation \(y = 3\sin x + 2\cos x\) for \(0°\leq x \leq 360°\).

(c) Use the graph to solve :

(i) \(3\sin x + 2\cos x = 0\)

(ii) \(2 + 2\cos x + 3\sin x = 0\).
