Example 1

easy
Find the amplitude of f(x)=5sinโก(x)f(x) = 5\sin(x).

Solution

  1. 1
    The general form of a sine function is f(x)=Asinโก(Bx+C)+Df(x) = A\sin(Bx + C) + D, where โˆฃAโˆฃ|A| is the amplitude.
  2. 2
    Here A=5A = 5, so the amplitude is โˆฃ5โˆฃ=5|5| = 5.
  3. 3
    This means the graph oscillates between y=โˆ’5y = -5 and y=5y = 5.

Answer

Amplitude=5\text{Amplitude} = 5
Amplitude is the distance from the midline to the maximum (or minimum) of a periodic function. For y=Asinโก(x)y = A\sin(x) or y=Acosโก(x)y = A\cos(x), the amplitude is โˆฃAโˆฃ|A|. It measures how far the wave deviates from its center position.

About Amplitude

Amplitude is the maximum vertical distance from the midline of a periodic function to a peak or trough.
