For the following exercises, sketch the graph of each function for two full periods. Determine the amplitude, the period, and the equation for the midline.
f(x) = −cos (x + π/3) +1
Consider the following expression:
f(x) = -cos(x + π/3) + 1
Use maple to plot the graph as follow:
Consider the graph plotted of f(x) = -cos(x + π/3) + 1,
General equation,
y = Acos(kx – c) + d
Then, period = 2π/|k|.
Since, is the periodic function with a period of 2π.
Hence, the amplitude is 2 and the period is 2π,
Thus, the midline in the graph is y = 0.5.
Hence, the amplitude is 2 and the period is 2π,
Thus, the midline in the graph is y = 0.5.
