4e Example 1 Part 2 (How to graph the Cosine Functions)

The video tutorial covers transformations of the cosine function, including amplitude, period, phase shift, and vertical shift. It explains how to graph these transformations and discusses reflections about the axes and the range of the cosine graph. The tutorial also covers phase shift and period adjustments, as well as double reflections and vertical shifts. Finally, it introduces the tangent graph and its transformations.

What is the significance of the B value in determining the period of a trigonometric function?

What is the maximum and minimum value of the cosine function after the transformations?

How does the reflection about the Y-axis affect the cosine graph?

How does the tangent graph differ from the sine and cosine graphs based on the text?
