Q5.a) Plot the graph of y = 3 tan⁡ x, for the range 0 ≤ x ≤ 1.2 in the intervals of 0.2

Note that the angle x is in radian measure. (10)

Suggested scales: horizontal axis 2 cm = 0.2

vertical axis 2 cm = 1

b) Using the same axes and scales, plot the graph of y = 3/2 π - 5x, for the range 0 ≤ x ≤ 0.9,

on the graph produced in Q5(a). (3)

c)Use the graphs plotted in Q5 (a)and Q5(b)to solve the equation 5x + 3 tan⁡ x = 3/2 π

for 0 ≤ x ≤ 1.2. (3)
