ANSWER
Midline y=-1
Period= 2π
Amplitude=3
Frequency=1
EXPLANATION
The given function completes one cycle on the interval 0 to 2π.
Therefore the period of the function is
[tex]2 \pi[/tex]
The midline divides the graph into two equal halves.
This line is y=-1
The cycle repeated once on the interval [0,2π] hence the frequency is 1.
The amplitude is the distance from the midline to the peak.
=2--1=3
