Chapter 4.PS, Problem 9PS

To determine

a)

To graph:

The model representing the blood pressure $P$ in millimeter of mercury) against the walks of the blood vessels of a patient.

$P=100-20\cos \frac{8\pi t}{3}$

To determine

b)

To find:

The period of the model representing the blood pressure $p$ (in millimeters of mercury) against the walls of the blood vessels of a patient.

$P=100-20\cos \frac{8\pi t}{3}$

To determine

c)

To find:

The amplitude of the model representing the blood pressure $p$ (in millimeters of mercury) against the walls of the blood vessels of a patient.

$P=100-20\cos \frac{8\pi t}{3}$

To determine

d)

To find:

The pulse of the patient with $P$ represent the model for the blood pressure (in millimeters of mercury) against the walls of the blood vessels of a patient.

$P=100-20\cos \left(\frac{8\pi t}{3}\right)$

To determine

e)

To find:

The necessary period that the patient heart beat must have. So that the pulse rate will be $64$ beats per minute or lesser and also to find the coefficient of $t$ that it must have.
