    Assignment:Find the solution set of inequality 278x <5000sinx .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        278 * x <5000 * sin x         (1)

---

    From inequality(1)：
         x < -14.746698 或  -13.407599 < x < -8.906699 或  -6.662673 < x < -2.975397 或  0 < x < 2.975397 或  6.662673 < x < 8.906699 或  x ＞ 13.407599

---

    The final solution set is :
         x < -14.746698 或  -13.407599 < x < -8.906699 或  -6.662673 < x < -2.975397 或  0 < x < 2.975397 或  6.662673 < x < 8.906699 或  x ＞ 13.407599
