What is a Sinusoidal Function? The family of sinusoidal functions applies to either sine or cosine waves since they are the same except for a horizontal change. The set of X coordinates of the unit circle is …

The graph of one complete period of a cosine curve is given. (a) Find the amplitude, period, and horizontal shift. (Assume the absolute value of the horizontal shift is less than the period.) amplitude …

The graph of one complete period of a sine or cosine curve is given. Write an equation that represents the curve in the form y = a sin k (x – b) or y = a cos k (x – b) yA 2 4 4 -2

The graph of a cosine function shows a reflection over the x-axis, an amplitude of 2, a period of 4, and a phase shift of 0.5 to the right. Which is the equation of the function described?

The graph of a cosine function has an amplitude of 3, a vertical shift of 1, and a period of 4. These are the only transformations of the parent function. Use the Sine tool to graph the function. The first point …
