The position of the top of a tine on a tuning fork in meters is given by:
where t is the time in seconds. Give the amplitude, period, and phase shift (displacement) for the function and graph the function through one full period. How many times does the tine oscillate in one second?
I know that the amplitude is 10^-3^ and the phase shift is pi/2, or I think it is. But do I have to distribute to find the period? And how do I find the oscillation?
