Best ResponseYou've already chosen the best response.0the reference angle for 3pi/4 is pi/4. pi/4 has the same sine and cosine. angles for which pi/4 is the reference angle will then have sines and cosines that are either equal or opposites depending on the quadrant. make sense so far?

Best ResponseYou've already chosen the best response.0So y will 1 as well since it is in quadrant 3, (x,y).
