For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2πt/t , where a is the amplitude and t is the period of the wave in seconds.

part 1: write an equation for the given function given the amplitude, period, phase shift, and vertical shift.
amplitude = 4 , period = 4π , phase shift = -4/3 π , vertical shift = -2

part 2: write an equation for the given function given the period, phase shift, and vertical shift.
cotangent function, period = π , phase shift = -1/3 π , vertical shift = 2
