Final answer:
To find the amplitude of a sine function, look at the equation of the function. The amplitude is the distance from the midline of the sine wave to its maximum or minimum value.
Step-by-step explanation:
To find the amplitude of a sine function, you can look at the equation of the function. The equation has the general form of y(x) = A sin(kx - wt + p), where A represents the amplitude. The amplitude is the distance from the midline of the sine wave to its maximum or minimum value.. The amplitude is the distance from the midline of the sine wave to its maximum or minimum value.
For example, in the equation y(x) = 0.2 m sin(6.28 m¯¹x – 1.57 s¯¹t), the amplitude is 0.2 m, which means the sine wave oscillates between +0.2 m and -0.2 m.
