Hi, I know this is. two part question but I have no idea how to answer it. I included all the information that I had! Thank you!!!

For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2nt , Where a is the amplitude and T is the period of the wave in seconds. 13. Write an equation for the given function given the amplitude, period, phase shift, and vertical shift. amplitude: 4, period = 41, phase shift = 3 vertical shift = -2 14. Write an equation for the given function given the period, phase shift, and vertical shift. cotangent function, period = I, phase shift = - - It, vertical shift = 2
