(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.
