Question

8.
A particular sound wave can be graphed using the function y = –3 sin x. Find the period of the function.

period = 2pi
period = –3
period = 3
period = 1/2

Answer 1

a sine function with frequency = 1 has the period of 2pi

Answer 2

If you are looking at y = A sin(Bx) or y = A cos(Bx), then the amplitude is A and the period is 2pi / B. Here, B is 1.

Answer 3

so its -3?

Answer 4

no
period = 2pi

Answer 5

ohh so A

Answer 6

yup a is correct
