а в фотомаче нету там всё решаются...

1. Cot(x/2) × Sin(x) ≥ 2π 2. |Sin(x) + Cos(x)| < 1/√2 3. Sin(2x) - √3Cos(2x) > √2 4. -2 ≤ Tan(x) < 1 5. 2Sin²(x) - 5Sin(x) + 2 > 0 6. Cot²(x) - Cot(x) - 2 ≤ 0 7. Cos²(2x)/Cos²(x) ≥ 3Tan(x) 8. Sin⁴(x) + Cos⁴(x) ≥ √3/2

1. Cot(x/2) × Sin(x) ≥ 2π
2. |Sin(x) + Cos(x)| < 1/√2
3. Sin(2x) - √3Cos(2x) > √2
4. -2 ≤ Tan(x) < 1
5. 2Sin²(x) - 5Sin(x) + 2 > 0
6. Cot²(x) - Cot(x) - 2 ≤ 0
7. Cos²(2x)/Cos²(x) ≥ 3Tan(x)
8. Sin⁴(x) + Cos⁴(x) ≥ √3/2
