The equation of the curve is given by y= 1+3 sin x.
(a) Complete the table below for y= 1+3 sin x.

(b)(i) On the grid provided, draw the graph of y= 2sin `x^0` and y= 1+3 sin x. For `0^0lexle360^0`
(ii) state the amplitude of the curve.
(c)On the same grid draw the graphs of y= tan x for `90^0lexle270^0`
(d)Use the graphs to solve the equation 1+3 sin x=tan x for `90^0lexle270^0`
