The pressures caused by pure tones on the eardrum are sinusoidal The change in pressure P in pounds per square foot on a person's eardrum from a pure tone at time t in seconds can be modeled using the equation PA sin (2x +4), wh per second, and is the phase angle. When P is positive, there is an Q increase in pressure and the eardrum is pushed inward, when P is negative, there is a decrease in pressure and the eardrum is pushed outward. A graph of a tone P(1)= 007 sin 2x(256 56t+is shown to the right. Complete parts (a) through (c) below. (a) Determine algebraically the values of t for which P=0 over [0, 005] The solution set is (). Round to five decimal places as needed. Use a comma to separate answers as needed.) 007 007 C
