The equation P = 100 + 20 sin 2t models a person's blood pressure P in millimeters of mercury. In this equation, t is time in seconds. The blood pressure oscillates 20 millimeters above and below 100 millimeters, which means that the person's blood pressure is 120 over 80. This function has a period of 1 second, which means that the person's heart beats 60 times a minute.
a. Find the blood pressure at t = 0, t = 0.25, t = 0.5, t = 0.75, and t= 1.
b. During the first second, when was the blood pressure at a maximum?
c. During the first second, when was the blood pressure at a minimum?
