Chapter 8.3, Problem 47E

(a)

To determine

Themaximum value of $P$ (called the systolic pressure) and the minimum value of $P$ (called the diastolic pressure) and one or two values of $t$, where these maximum and minimum values of $P$ occur for a person’s blood pressure $P$ at time $t$ (in seconds) given by equation $P=100+20\cos 6t$.

(b)

To determine

Approximately, how many heartbeats per minute are predicted by the equation $P=100+20\cos 6t$, if time is measured in seconds.
