    Assignment:Find the solution set of inequality x(sinx＋1) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * ( sin x + 1 ) >0         (1)

---

    From inequality(1)：
         0 < x < 4712389/1000000 或  4712389/1000000 < x < 5497787/500000 或  x ＞ 5497787/500000

---

    The final solution set is :
         0 < x < 4712389/1000000 或  4712389/1000000 < x < 5497787/500000 或  x ＞ 5497787/500000
