Chapter 8.3, Problem 78E

(a)

To determine

To calculate: The time for one full respiratory cycle if the velocity of airflow is $v=1.75\sin \frac{\pi t}{2}$.

(b)

To determine

To calculate: The number of cycles per minute if the velocity of airflow into and out from the lungs is $v=1.75\sin \frac{\pi t}{2}$.

(c)

To determine

To calculate: The velocities of airflow when $t=2$ and $t=3$ if the velocity of airflow into and out from the lungs is $v=1.75\sin \frac{\pi t}{2}$.

(d)

To determine

To calculate: The velocity of airflow when $t=1.5$ if the velocity of airflow into and out from the lungs is $v=1.75\sin \frac{\pi t}{2}$.

(e)

To determine

To graph: The graph of the function if the velocity of airflow into and out from the lungs is $v=1.75\sin \frac{\pi t}{2}$.
