sin -x = -sin x
Can you do it now?

@FaiqRaees  So one of the answers would be B. then, right? What about the cosine that is equivalent to that?

faiqraees · Answer

-sin x = cos (x +pi/2)

faiqraees · Answer

Can you figure it out?

kelsey.benton00 · Answer

@FaiqRaees  Would the answers be B. and C.?

faiqraees · Answer

Yes

faiqraees · Answer

Btw the easy way was to just look at the y-intercepts in the equation
