Master Graphing the cosine function with a Phase Shift

The video tutorial explains how to graph cosine functions with phase shifts. It covers the transformations that affect the graph, such as amplitude, period, and phase shift. The tutorial provides step-by-step examples, including how to handle reflections over the x-axis. Key concepts like identifying the amplitude and determining the period are discussed, along with practical graphing techniques.
