Finding the equation of a periodic function from a graph or sketch

Описание к видео Finding the equation of a periodic function from a graph or sketch

In this video we apply the standard equation of a periodic function to finding the equation from a sketch or graph. This particular example uses a cosine graph but is equally applicable to a sine graph. We cover amplitude, period, phase shift or horizontal shift as well as vertical shift. Want more videos?
