Question:

Suppose the A key above Middle C is played as a pure tone. For this tone, P(t) = 0.002 sin9880πt), where P(t) is the change of pressure (in pounds per square foot) on a person’s eardrum at time t (in seconds).

(a) Graph this function on [0, 0.003].
(b) Determine analytically the values of t for which P = 0 on [0, 0.003] and check graphically.
(c) Determine the period T of P(t) and the frequency of the A note.
