The height of the tip of an airplane propeller above the ground once the airplane reaches full speed can be modelled by a sine function. At full speed, the propeller makes 200 revolutions per second. At t = 0, the tip of the propeller is at its minimum height above the ground. Determine whether the instantaneous rate of change in height at t = 1/300 is a negative value, a positive value, or zero.
