    Arrow Trignometric function (graph)

    The vertical displacement
    y of a boat that is rocking up and down on a lake. y was measured relative to the bottom of the lake. It has a maximum displacement of 12 meters and a minimum of 8 meters, a period of 3 seconds, and an initial displacement of 11 meters when measurement was first started (i.e., t = 0). assume at t = 0 function is increasing.

    ---> full period = 6 secs
    therefore, b = 2 pi / 6 = pi/3
    Amplitude = 2
    D = 10

    I'm just getting confused with the initial displacement of 11 m. Anyone please help me out

    Well, what do you have so far? If there were no initial displacement, if the initial displacement were 0, what would your answer be?
