a) Complete the table below.

b) Draw the graphs of y = 2sin (½ x – 30)⁰and y = ½ Cos 2x for -180⁰≤ x ≤ 180⁰. Use a scale of 2cm for 45^o on x-axis and 1cm to 0.5 units on y-axis.
c) Use your graph to solve the equations.
i) 2 sin (½ x – 30) = 0.55
ii) 4 sin (½ x – 30) – Cos 2x = 0
d) State period of the equation y = 2 sin (½ x – 30)^o.
