I'm trying to figure out how to do this problem, but don't know where to begin. I think some information is missing.
The function P=120+30Sin 2pi(t) models the blood pressure (in millimeters of mercury) for a person who has a high blood pressure of 150/90; t represents seconds.
a. What is the pressure of this function?
b. How many heartbeats are there each minute?
