I have a couple questions when it comes to this, but it say to find the cos ( -270 ). I think the coordinates are ( 0, 1 ) idk what to do after this. ...Help? Please?

Find a coterminal for -270 between 0 and 360. $\displaystyle -270 + 360 = 90$ From the unit circle, $\displaystyle \cos{90}$ is 0, because, as you said, the coordinates are (0,1). The points are in this form: $\displaystyle P(\cos\theta, \sin\theta)$
wouldnt it just be zero then? cuz cos is focused on the x...and its ( 0, 1 )
