Question

I give Medals!! Posting question as file...

Answer 1

ok waiting for the file.

Answer 2

Here it is

Answer 3

any thoughts?

Answer 4

Sorry:( im not in trig yet.

Answer 5

then why are you doing a trig question?

Answer 6

I was waiting for the file because they said they needed help than it was trig so I told her I couldn't do it @amistre64

Answer 7

the picture gives us enough information for an amplitude, and a period rate, and the shape conforms to a standard trig function ...

oh, lol i had confused you with the poster :)

Answer 8

@Jamie_elizabeh sorry, i confused you with the original poster :)

Answer 9

I figured that. Its fine

Answer 10

Thanks Jamie for trying Okay Amistre can you help?

Answer 11

yw

Answer 12

i can, but i need to know how much of this you understand to start with. maybe your just unsure but actually know it

Answer 13

in some graded programs they expect the answer in terms of sin .... if we can use other trig functions here that will be helpful to us

Answer 14

okay I'm completely lost at this point lol

Answer 15

then lets try to remember some definitions ... and basic graphs of sin/cos

how would you define the term: amplitude?

Answer 16

how high it is?

Answer 17

yes, but its better to remember it as half the total height

Answer 18

if we assume y=6 is a midline, then would you agree that 6 is the amplitude?

Answer 19

a trig function has some basic parts to it ..

g = A trig(P(x-ph)) + K

A is the amplitude, trig is the name of a trig function

P is the period adjustment

ph is a phase shift

K is a vertical transition that moves the whole thing up or down

Answer 20

lets A = 6, and since the midline is normally y=0, let K = 6 as well

g = 6 trig(P(x-ph)) + 6

it may be useful to define the trig function name, and that can be done by comparing the shape of the graph
