If cos (2 sin -1 x) = 1 9 , then x = (A) Only 2 3 (B) Only - 2 3 (C) 2 3 , - 2 3 (D) Neither 2 3 nor - 2 3 7. cot -1 1 1 1 1 - + + - - + sin sin sin sin x x x x = (A) π - x (B) 2 π - x (C) x 2 (D) π - x 2 8. sin (2 sin -1 0.8) = (A) 0.96 (B) 0.48 (C) 0.64 (D) None of these 9. If cos - 1 x + cos - 1 y + cos - 1 z = π , then (A) x 2 + y 2 + z 2 + xyz = 0 (B) x 2 + y 2 + z 2 + 2xyz = 0 (C) x 2 + y 2 + z 2 + xyz = 1 (D) x 2 + y 2 + z 2 + zx - 1 = 0 11. tan 2 1 5 4 1 tan - - π = (A) 17 7 (B) - 17 7 (C) 7 17 (D) - 7 17 14. If tan - 1 2x + tan - 1 3x = π 4 , then x = (A) - 1 (B) 1 6 (C) - 1, 1 6 (D) None of these 15. The principal value of, sin - 1 sin 2 3 π is : (A) - 2 3 π (B) 2 3 π (C) 4 3 π
