[ 1/1Inequality]
    Assignment:Find the solution set of inequality 172 <= 5000*(x-sinx) <= 602 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        172 <= 5000 * ( x - sin x )         (1)
         5000 * ( x - sin x ) <= 602         (2)

---

    From inequality(1)：
         x ≥ 0.594469
    From inequality(2)：
         x ≤ 0.909751

---

    From inequalities (1) and (2)
         0.594469 ≤ x ≤ 0.909751    (3)

---

    The final solution set is :
         0.594469 ≤ x ≤ 0.909751
