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.

What happens to the graph of cosine when the phase shift is negative?

Illustrate how to determine the start and end points of a cosine graph with a phase shift.

Discuss the relationship between the period of a cosine function and its phase shift.
