Thread: Equation of axis of a periodic function!

I am confused on how to find it. Is it the amplitude of the periodic function or what?

For instance i have a periodic function that is 6m between two points so amplitude = 3 and does that mean the equation of axis is y=3 ?

any help is appreciated! and thanks in advance!

what is the function, specifically?

sin function for instance

depends on the vertical shift

I would imagine the axis of a periodic function (never heard it called this before) is the same as the midline ... y = 4 in the case you provided.

how did u calculate y=4, because i got y=3 ( same as the amplitude? )

what value is halfway between y = 7 (max) and y = 1 (min) ?

3

how far is 3 from 7?

how far is 3 from 1?

are they equal?

oh okay thank you!
