Question:

When tuning a piano, a technician strikes a tuning fork for the A above middle C and sets up a wave motion that can be approximated by y = 0.001 sin 880πt, where t is the time (in seconds).
(a) What is the period of the function?
(b) The frequency f is given by f = 1/p. What is the frequency of the note?
