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 850πt,

Where t is the time (in seconds).

The frequency is given by f = 1 / p.What is the frequency of the note?

A)85 cycles/sec
B) cycles/sec
C) cycles/sec
D)850 cycles/sec
E)425 cycles/sec
