A particular sound wave can be graphed using the function y=1 sin 4x. Find the amplitude and period of the function

The amplitude is equivalent to the coefficient of the sine function, so:

Amplitude = 1

The time period of a Sin (x) = 2π

The time period of Sin (4x) = 2π/4 = π/2

The period is π/2

Amplitude=1

period = pi/2
