The frequency of a trigonometric function is the number of complete cycles contained in its graph between any two angles that are 360 degrees apart. The period of a trigonometric function is the number of degrees contained in one complete cycle of its graph. A phase shift of a function is a shift of the function to the left or right. For example, we can obtain the sine graph from the cosine graph by a phase shift of 90 degrees. Click the link below to check your answers.
