Math question: Find the amplitude of the sine function f(x) = sin(x).Answer: The amplitude of the sine function f(x) = sin(x) is 1, as the maximum value of sin(x) is 1, and the minimum value is -1. Thus, the difference between the maximum and minimum values, which represents the amplitude, is 1. Using the
