Amplitude
Definition of Amplitude
- Amplitude is half the distance between the minimum and maximum values of the range of a periodic function with a bounded range.
- In other words, for functions of the form y = A sin bθ or
y = A cos bθ, the amplitude is |A|.
Examples of Amplitude
Solved Example on Amplitude
Find the amplitude of the function
.
Choices:
A. - 4
B. 4

D. - 3
Correct Answer: B
Solution:
Step 1: Recall that "for functions of the form y = A cos bθ, the amplitude is |A|."
Step 2: So, 4 is the amplitude of the given function.
