For a "signal" , the amplitude isOriginally Posted by cheesepie
, the period is , and the initial phase is .
In this case we have:
,
so the amplitude is , the period is ,
and the initial phase is .

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
v=12sin(120pi(t)+0.5pi)
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
any step ?
