Sin (x+pi/3) ≤ 1/2

помогите

Решение

sin (x + π/3) ≤ 1/2

- π - arcsin (1/2) + 2πn ≤ x + π/3 ≤ arcsin (1/2) + 2πn, n ∈ Z

- π - π/6 + 2πn ≤ x + π/3 ≤ π/6 + 2πn, n ∈ Z

- 7π/6 + 2πn ≤ x + π/3 ≤ π/6 + 2πn, n ∈ Z

- 7π/6 - π/3 + 2πn ≤ x ≤ π/6 - π/3 + 2πn, n ∈ Z

- 3π/2 + 2πn ≤ x ≤ - π/6 + 2πn, n ∈ Z
