How does phase shift affect your graph

The video tutorial explains the concept of phase shift in trigonometric functions, focusing on the cosine function. It covers how to graph the cosine function, calculate phase shifts, and understand their effects on the graph. The tutorial also discusses how phase shifts can alter the period of the function, providing examples and calculations to illustrate these changes.
