Question

A particular sound wave can be graphed using the function y= 7 sin x. Find the amplitude and period of function.

Answer 1

Ampliftude = 7

period = 2pi

Explanation:

If we have a sine function of the form

`y=A\sin ax`

then the amplitude is A and the period is

`(2\pi)/(a)`

Now, in our case, we have

`y=7\sin x`

meaning

Ampltude = 7 and

period = 2pi / 1 = 2 pi.

which are our answers!
