A sound wave is modeled with the equation y = 1/4 cos 2 pi/3 theta
a. Find the period. Explain your method.
Clarify the argument of the cosine.
----------------
b. Find the amplitude. Explain your method.
Amp = 1/4
It's the multiplier.
-------------------------
c. What is the equation of the midline?
y = 0
What does it represent?
The neutral position.
