I figured it out :D

dan815 · Answer

4 to 36 its osccilating, can you tell me what the period is

anonymous · Answer

I believe that the amplitude is 36-4/2 = 16, Period = 36 and 1/4 wave =  36/4 = 9

dan815 · Answer

oh nvm

anonymous · Answer

Am I correct @dan815 ?

dan815 · Answer

the period is only 12, period is the time for just 1 cycle, or 1 pattern

dan815 · Answer

now you have to also consider the shift and determine if its a sin or cos

anonymous · Answer

I believe its sin because it doesn't have curves like cos @dan815

dan815 · Answer

remember that sin starts from 0 but this seems to be starting from the most negative point possible kind of like a -cos graph

anonymous · Answer

Hmm..

anonymous · Answer

When you put it that way, would it be cos?

dan815 · Answer

now u still need it in sin so u must do a phase shift

dan815 · Answer

to account for that

anonymous · Answer

Can you help me on how I would do that?
