4. (a) (i) Sketch the curve \(y = \sin ( x - 30 ) ^ { \circ }\) for \(x\) in the interval \(- 180 \leq x \leq 180\).
(ii) Write down the coordinates of the turning points of the curve in this interval.
(b) Find all values of \(x\) in the interval \(- 180 \leq x \leq 180\) for which $$\sin ( x - 30 ) ^ { \circ } = 0.35$$ giving your answers to 1 decimal place.
