Find the Exact Value sin (67.5) sin(67.5) sin ( 67.5) Rewrite 67.5 67.5 as an angle where the values of the six trigonometric functions are known divided by 2 2. sin(135 2) sin ( 135 2) Apply the sine half - angle identity. ±√ 1−cos(135) 2 ± 1 - cos ( 135) 2. Change the ± ± to + + because sine is positive in the first quadrant., cos(−15o) =0.9659 Explanation: cos(−15o)= cos(30o −45o) = cos30ocos45⊕sin30osin45o ... Calculate the value of the cos of 1.5 ° To enter an angle in radians, enter cos (1.5RAD) cos (1.5 °) = 0.999657324975557 Cosine the trigonometric function that is equal to the ratio of the side ...
