    Sinusoidal function

    Sketch a height versus time graph of the sinusoidal function that models each situation. Draw at least three cycles. Assume that the first point is at the lowest possible height.
    1) a water wheel with a. Radius of 3m whose centre is at water level and that rotates once every 40s ?

    How am i suppose to make the graph what is the diameter going to be :/

    If the radius of the water wheel is 3 m, then the diameter of the water wheel is 6 m, of course. Was that the diameter you meant?

    The problem says you should take the "first point" (which I interpret to mean t= 0) at the lowest point Since the center is a water level and the water wheel has radius 3m, initially the point on the water wheel is 3 m below the water. After 20 seconds, it will be 3 m above the water. Do you see why? When will it be at water level?
