How does the amplitude affect your sine and cosine graphs

The video tutorial explains how amplitude affects trigonometric graphs, focusing on the sine function. It begins with an introduction to amplitude and its role in graphing. The instructor graphs the sine function, highlighting its initial period and critical points. The concept of amplitude as the absolute value of 'a' is discussed, showing how it influences the graph's vertical stretch or compression. Examples with different amplitudes, both greater and less than 1, are provided to illustrate these effects. The tutorial concludes by summarizing the impact of amplitude on sine and cosine graphs.
