Question

Write the word or phrase that best completes each statement or answers the question.
-Before exercising, an athlete measures her air flow and obtains
$$a = 0.65 \sin \left( \frac { 2 \pi } { 5 } t \right)$$ where a is measured in liters per second and t is the time in seconds. If a > 0, the athlete is inhaling; if a < 0, the athlete
is exhaling. The time to complete one complete inhalation/exhalation sequence is a respiratory cycle.
What is the amplitude? What is the period? What is the respiratory cycle?
Graph a over two periods beginning at t = 0.
