Question

If x takes all permissible negative values, then sin - 1 ⁡ x is equal to, - cos - 1 ⁡ 1 - x 2, cos - 1 ⁡ x 2 - 1, π - cos - 1 ⁡ 1 - x 2, cos - 1 ⁡ 1 - x 2

MARKS App · Accepted Answer

Let x = - y , y > 0 ∴ sin - 1 ⁡ x = sin - 1 ⁡ - y = - sin - 1 ⁡ y = - cos - 1 ⁡ 1 - y 2 = - cos - 1 ⁡ 1 - x 2
