    Assignment:Find the solution set of inequality 1320.270 ≤2×14300×0.125×（sin（180×x））^3÷3+3575x×（1-sin（180×2x)/(6.283x))×0.4375×(sin（180×x)+sin（180×(1.25-2x)))÷（1.25-3x) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1320.270 ≤2 × 14300 × 0.125 × ( sin ( 180 × x ) ) ^ 3 ÷ 3 + 3575 * x × ( 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)：
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!    (3)

---

    The final solution set is :
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
