What is the definition of amplitude in math?
Let's see what vocabulary is needed to discuss sinusoids and other trigonometric graphs. amplitude: The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function. Amplitude is the magnitude (height) of the oscillation (wave) of a sinusoidal function.Sometimes it is referred to as the peak from center of the graph. The maximum of y = sin x is 1.et's see what vocabulary is needed to discuss sinusoids and other trigonometric graphs. amplitude: The amplitude of a sinusoidal function is one-half of the positive difference between the maximum and minimum values of a function.
