Question

I just began a chapter on trigonometric functions and graphing them. Instructions for the worksheet:
Determine the amplitude, period, and frequency of the function.
Problem: y=3sin(x/2)

Answer 1

the period for sin(x) is 2π
the period for sin(x/2) is 4π

Answer 2

And what about the frequency and amplitude?

Answer 3

Sorry I don't know ANYTHING about this, its my final assignment ever and we didn't learn anything about it.

Answer 4

well the amplitude for the sin(x) is 1
amplitude for 3sin(x) is 3

Answer 5

And frequency, isn't that the reciprocal of the period?

Answer 6

yeap
