Question 926729: cos θ =12/13, 270°<θ<360° find the exact value of each of the remaining trigonometric functions of θ
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
270°<θ<360° means the angle is in the 4th quadrant
where the cos is positive
If I say cos = b/c and sin = a/c, I can also say:
( it's in the 4th quadrant )
