Graphs
of Trigonometric Functions
 Sketch the curves of:
(i) y = 1.5 + 0.5 | cos x |
Answer
(ii) y = 1 + 3 | sin 2x |
Answer
(iii) y = 2 - 2 | cos 2x |
Answer
Sketch
the graph of the function
f(x) = 2 |cos (x + p/2)|
for the domain
 .
Answer
Sketch
the curve y = |1 + 3 sin 2x| for values of x between 0 and p
inclusive.
State the range of values of y in this domain.
By adding a suitable line to the same diagram, state, for the above domain,
the number of solutions to the equation
p
|1 + 3 sin2x| = 4 (p
- x)
Answer
Sketch
the curve y = 2 + 2 sin x for the domain
By sketching a suitable straight line on the same axes, state the number of
roots to the equation
3p
sin x + 4x = 3p
