The angle "phi" represents the phase shift, determined by the initial conditions of the experiment or the position of the weight at t = 0. if the weight is at its maximum positive position (weight is above equilibrium) at t = 0, then "phi" = 0. if the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then "phi"=pi . if the weight is traveling in the negative direction and passing through equilibrium at t = 0, then "phi"=pi/2. in the response box, describe the initial condition of our experiment; specifically, describe the position of the weight and the direction in which it was traveling.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
