WebApr 24, 2016 · Explanation: The angle 2π 3 is in the 2nd quadrant. where the cos ratio has a negative value. The related 'acute angle' to 2π 3 = (π− 2π 3) = π 3. ⇒ cos( 2π 3) = − cos( … WebKey Concepts. The sine and cosine of an angle have the same absolute value as the sine and cosine of its reference angle. The signs of the sine and cosine are determined from the x– and y-values in the quadrant of the original angle.; An angle’s reference angle is the size angle, [latex]t[/latex], formed by the terminal side of the angle [latex]t[/latex] and the … インスタ pc dm
