    Assignment:Find the solution set of inequality 880.180 ≤2×14300×0.125×（sin（180×x））^3÷3+1125.5x×（1-sin（180×2x)/(6.283x))×0.4375×(sin（180×x)+sin（180×(1.25-2x)))÷（3.1416×（1.25-3x)) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        880.180 ≤2 × 14300 × 0.125 × ( sin ( 180 × x ) ) ^ 3 ÷ 3 + 1125.5 * x × ( 1 - sin ( 180 × 2 * x ) / ( 6.283 * x ) ) × 0.4375 × ( sin ( 180 × x ) + sin ( 180 × ( 1.25 - 2 * x ) ) ) ÷ ( 3.1416 × ( 1.25 - 3 * x ) )         (1)
        From the definition field of divisor
         6.283 * x ≠ 0        (2 )

    From inequality(1)：
         -0.552021 ≤ x ≤ -0.547518 或  -0.547518 ≤ x ≤ 0.006352 或  0.006352 ≤ x ≤ 0.011319 或  x ≥ 0.291529
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         -0.552021 ≤ x ≤ -0.547518 或  -0.547518 ≤ x < 0 或  0 < x ≤ 0.006352 或  0.006352 ≤ x ≤ 0.011319 或  x ≥ 0.291529    (3)

---

    The final solution set is :
         -0.552021 ≤ x ≤ -0.547518 或  -0.547518 ≤ x < 0 或  0 < x ≤ 0.006352 或  0.006352 ≤ x ≤ 0.011319 或  x ≥ 0.291529
