When Hyperventilating, a Person Breathes in and Out Extremely Rapidly $V = 3 - 0.06 \cos ( 200 \pi t )$

Short Answer

When hyperventilating, a person breathes in and out extremely rapidly.A spirogram is a machine that draws a graph of the volume of air in a person's lungs as a function of time.During hyperventilation, the spirogram trace may be represented by $V = 3 - 0.06 \cos ( 200 \pi t )$ , where V is the volume of the lungs in liters and t is the time in minutes.What is the maximum volume of air in the lungs?
