Answer each of the following questions in one word or one sentence or as per exact requirement of the question:Write the value of sin–1(1550°).

Given sin-1 (sin 1550°)

= sin-1 (sin (1440° + 110°))

= sin-1 (sin (360° × 4 + 110°))

We know that sin (2nπ + θ) = sin θ

= sin-1 (sin 110°)

We know that sin-1 (sin θ) = π – θ, if θ [π/2, 3π/2]

= 180° - 110°

= 70°

sin-1 (sin 1550°) = 70°
