(a) Copy and complete the table for the relation: $y=2\cos x+3\sin x$ for $0°\le x\le 360°$.

x	0°	30°	60°	90°	120°	150°	180°	210°
y	2.00	3.23			1.60			-3.23

(b) Using a scale of 2 cm to 60° on the x- axis and 2 cm to one unit on the y- axis, draw the graph of $y=2\cos x+3\sin x$ for $0°\le x\le 360°$.
(c) From the graph, find the : (i) maximum value of y, correct to two decimal places ; (ii) solution of the equation $\frac{2}{3}\cos x+\sin x=\frac{5}{6}$.
