6.1 Determine the general solution for sin(x – 30°) = cos 2x
6.2 Consider the function f (x)= sin(x – 30°) and g(x) = cos 2x
6.2.1 Write down the period of g
6.2.2 State the range of f
6.2.3 On the grid provided in the ANSWER BOOK, draw a graph of f and g for x ∈ [-90° ; 180°].
Clearly show all intercepts with the axes, turning point and end points.
6.3.4 Write down the x-coordinates of the point of intersection of f and g in the interval of x ∈ [-90° ; 180°]
