[ 1/1Inequality]
    Assignment:Find the solution set of inequality （1÷D÷D）＋（3.2÷D÷D÷D） ≤3500×π÷6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 ÷ D ÷ D ) + ( 3.2 ÷ D ÷ D ÷ D ) ≤3500 × π ÷ 6         (1)

---

    From inequality(1)：
         D ≤ 0 或  D ≥ 0.121929

---

    The final solution set is :
         D ≤ 0 或  D ≥ 0.121929
