How do you find the amplitude of the sine and cosine graph

The video tutorial explains the concept of amplitude in the context of music and mathematics. It begins by introducing amplitude and its relevance to sound and music. The tutorial then defines amplitude as the half distance between the minimum and maximum values of a graph. It demonstrates how to determine amplitude using sine and cosine graphs, emphasizing that the amplitude is the absolute value of the coefficient in the function's equation. Examples are provided to illustrate how to calculate amplitude for different functions, concluding with a reminder that amplitude is unaffected by negative coefficients.
