Question

Consider the graph of the cosine function shown below. (will attach picture)

a. Find the period and amplitude of the cosine function.
b. At what values of θ for 0 < θ < 2pi do the maximum value(s), minimum values(s), and zeros occur?

Answer 1

Period=pi
Amplitude=4

Answer 2

got it?

Answer 3

yes thanks you

Answer 4

When theta=0, pi ,2pi -----> MAXIMUM
when theta= pi/4 , 3pi/4 , 5pi/4 and 8pi/4 -----> ZERO
when theta=pi/2 and 3pi/2---------->minimum

Answer 5

got it?

Answer 6

yes
