Those are part of the question.

Vocaloid (vocaloid):

any ideas? do you know what the cos graph looks like?

OpenStudy (liv1234):

I'm not sure, but I was thinking it might be option C? I know that's probably wrong.

Vocaloid (vocaloid):

OpenStudy (liv1234):

It sort of looks like option B?

Vocaloid (vocaloid):

Vocaloid (vocaloid):
