Complete the table given below for the functions y=-3 cos`2^0` and y=2sin(`2/3 x^0+30`) for `0^0lexle180^0`

(a) Using the grid provided, draw the graph of y=- 3 cos `2^0` and y=2 sin(`2/3 x^0+30`) on the same axis. Take 1 cm to represent `20^0` on the xaxis and 2 cm to represent one unit on the y- axis.
(b) From the graph, find the roots of 3 cos `2^0`+2 sin(`2/3 x^0+30`)
