Question

Assume that 3 . 13 ≤ π ≤ 3 . 15 . The integer closest to the value of sin - 1 ( sin 1 cos 4 + cos 1 sin 4 ) , where 1 and 4 appearing in sin and cos are given in radians, is:, - 1, 1, 3, 5

MARKS App · Accepted Answer

θ = sin - 1 ( sin 5 ) = - ( 2 π - 5 ) = 5 - 2 π ≈ - 1 . 26 as π ≈ 3 . 13
