6.3.2 Sketching 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:
