Master Graphing Sine with a Change in Amplitude

The video tutorial explains how to graph sine functions by identifying and adjusting the amplitude. It covers the process of graphing two periods of a sine wave, first with an amplitude of 4 and then with an amplitude of 1/3. The tutorial emphasizes the importance of understanding amplitude as the vertical stretch or compression of the graph, while noting that critical points remain unchanged. The video aims to help learners visualize how changes in amplitude affect the shape of the sine wave.

Describe the process of graphing two periods of the sine function.

What is the amplitude of the sine function discussed in the text?

How do you identify the maximum and minimum points of the sine graph?

Explain the significance of the critical points in graphing the sine function.

How does the amplitude affect the height of the sine graph?

What happens to the graph when the amplitude is less than one?

What is the relationship between the amplitude and the vertical stretching or compressing of the graph?
