Question

A particular sound wave can be graphed using the function y = 1 sin 2x. Find the amplitude of the function.

Answer 1

Amplitude is defined by y=a*sin(b*x+c)+d
where a=amplitude
period is represented usually by a T and there T= 2pi/b
the Phase shift is c/b

Think you can now figure out what the amplitude is or do you still need some help?

Answer 2

I think it is 1

Answer 3

Yes, that is correct. Good job.

Answer 4

thank you
