5.3.2 To Sketch Graphs of Trigonometric Functions

Example 1:
Sketch the graph of each of the following trigonometric functions for π £ x £ 2π.
(a) y = 3 sin x                                                (b) y = 2 cos x
(c) y = sin x + 1                                             (d) y = cos x –1  
(e) y = sin 2x                                                 (f) = cos 2x
(g) y = –sin x                                                 (h) y = –cos x
(i) y = | sin x |                                                 (j) y = | cos x |
(k) y = tan 2x

Solution:
