3.1 Consider the function y = 2tan x.
3.1.1 Make a neat sketch of y = 2tan x for 0 ≤ x ≤ 360 on the axes provided on the DIAGRAM SHEET. Clearly indicate on your sketch the intercepts with the axes and the asymptotes.
3.1.2 If the graph of y = 2tan x is reflected about the x-axis and shifted downwards by one unit, write down the equation of the new graph obtained by this transformation. (2)
3.2 The diagram below shows the graph of g(x) = a sin x for 0 ≤ x ≤ 360.
