(a) Complete the table given below by filling in the blank spaces.

(b) On the grid provided draw, on the same axes, the graph of y=3 cos 2x and y = 2sin`(2x+30^0)` for `0^0lexle180^0` Take the scale 1 cm for `15^0` on the x-axis and 2 cm for 1 unit on the y-axis,
(c) Use the graph to estimate the range of values of x for which 3cos`2xlesin(2x+30^0)` Give your answer to the nearest degree.
