If sin−1(sin(8π3))−cos−1(cos(17π3))=α then the positive value – InterviewSolution

1.	If sin−1(sin(8π3))−cos−1(cos(17π3))=α then the positive value of λ which satisfies the equation αλ3+λ2+λ−2=α is
Answer» $If {sin}^{- 1} (sin (\frac{8 π}{3})) - {cos}^{- 1} (cos (\frac{17 π}{3})) = α$ then the positive value of $λ$ which satisfies the equation $α λ^{3} + λ^{2} + λ - 2 = α$ is
