(a) Copy and complete the table of values for the relation y = 3 sin 2x. 

x	o\(^o\)	15\(^o\)	30\(^o\)	45\(^o\)	60\(^o\)	75\(^o\)	90\(^o\)	105\(^o\)	120\(^o\)	135\(^o\)	\(^o\)
y	0.0					1.5					-2.6

 

(b) Using a scale of 2 cm to 15° on the x-axis and 2cm to I unit on the y-axis, draw the graph of y = 3 sin 2x for 0° \(\geq\) x \(\geq\) 150°.

(c) Use the graph to find the truth set of;

(i) 3 sin 2x + 2 = 0;

(ii ) \(\frac{3}{2}\) sin 2x = 0.25.
