What is the amplitude of trigonometric function?
The amplitude of trigonometric function is the amplitude of function vibration, that is, the maximum distance from the equilibrium position, such as y = asinx(a >;; 0) A Here is the amplitude. The formula is A=(ymax-ymin)/2, and the maximum value minus the minimum value is divided by 2.

Trigonometric function is one of the basic elementary functions, which takes the angle (the most commonly used radian system in mathematics, the same below) as the independent variable, and the angle corresponds to the coordinates where the terminal edge of any angle intersects with the unit circle or its ratio as the dependent variable. It can also be equivalently defined as the lengths of various line segments related to the unit circle.
