What is the amplitude of a trigonometric graph

The video tutorial explains the concept of amplitude as the half distance between the maximum and minimum values of a graph. It discusses how amplitude is represented by the absolute value of a factor and explores transformations of functions, particularly focusing on the sine function. The tutorial demonstrates how multiplying the sine function by different factors affects its graph, showing horizontal stretching and compression. The video concludes by summarizing the effects of amplitude on the graph and its representation.
