Solve the problem.Before exercising, an athlete measures her air flow and obtains a = 0.65 sin 
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.
