The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. how is michael jackson kids whiteWebbCorrect option is D) As cos3x=4cos 3x−3cosx. ⇒3cos −1x=cos −1(4x 3−3x) ∴a=0 and b=3. or a=2nπ and b=3.
