5.3.2 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
(b) y = 2 cos x
(c) y = sin x + 1
(d) y = cos x –1
(e) y = sin 2x
(f) y = cos 2x
(d) y = cos x –1
(e) y = sin 2x
(f) y = cos 2x
Solution:
(a)
