    Assignment:Find the solution set of inequality 880.180 ≤2×14300×0.5^3×（sin（180×x））^3÷3+14300×0.27×0.5^2×（1-sin（180×2×x)/(6.283×x))×（0.4375）×(sin（180×x)+sin（180×(1.25-2×x)))÷（1.25-3×x) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        880.180 ≤2 × 14300 × 0.5 ^ 3 × ( sin ( 180 × x ) ) ^ 3 ÷ 3 + 14300 × 0.27 × 0.5 ^ 2 × ( 1 - sin ( 180 × 2 × x ) / ( 6.283 × x ) ) × ( 0.4375 ) × ( sin ( 180 × x ) + sin ( 180 × ( 1.25 - 2 × x ) ) ) ÷ ( 1.25 - 3 × x )         (1)
        From the definition field of divisor
         6.283 × x ≠ 0        (2 )

---

    From inequality(1)：
         -0.030723 ≤ x ≤ 0.02292
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         -0.030723 ≤ x < 0 或  0 < x ≤ 0.02292     (3)

---

    The final solution set is :
         -0.030723 ≤ x < 0 或  0 < x ≤ 0.02292
