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.
