find steady state equation from graph

provide working out

found w = 1000

amplitude = 24

Construct a cosine function to represent a plot of a sinusoid Consider the plot of a sinusoidal current source shown here. Express this sinusoidal current as a function in the form A cos (omega t + phi), where A is the magnitude, omega is the frequency in radians/second, and phi is the phase angle in degree , all of which can be expressed as integers. Several helpful values from the plot are given in the table next to the plot. Enter your answer as a function of t,i(t) =_. For example, i(t) = .Asin(t), t >= 0 s. Ensure that you use the degree symbol available in the drop-down menu that has trigonometric functions.

Explanation / Answer

24*cos(2000*pi*t + arccos(21.651/24)) = 24*cos(2000*pi*t +0.446)
