[ 1/1Inequality]
    Assignment:Find the solution set of inequality 437.09 ≤(2÷3×14.3×500^3×(sinπx)^3)+((14.3×500^2×x×(1-(sin2πx)÷2πx))÷(1.25-3x)×500×(sinπx+sinπ×(1.25-2x))) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        437.09 ≤ ( 2 ÷ 3 × 14.3 × 500 ^ 3 × ( sin π * x ) ^ 3 ) + ( ( 14.3 × 500 ^ 2 × x × ( 1 - ( sin 2 * π * x ) ÷ 2 * π * x ) ) ÷ ( 1.25 - 3 * x ) × 500 × ( sin π * x + sin π × ( 1.25 - 2 * x ) ) )         (1)

---

    From inequality(1)：
         x ≤ -1100.804906

---

    The final solution set is :
         x ≤ -1100.804906
