1)At a certain point in the ocean , the veritcal displacement of the water due to wave action is given by y= 3sin[pi/6(t-5)],where y is measured in meters and t is in seconds.
(a)Determine the amplitude ,period, and phase shift for the graph of this wave action.
(b)Sketch one complete cycle of this function.
2)In an ac circuit with only a constant inductance, the voltage is given by
a)Determine the amplitude ,period, and vertical displacement of this function
b)Sketch the graph of this function for one period.Make sure that you label the times on the x-axis where the graph crosses the axis and where it is at its highest and lowest points
