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

---

    From inequality(1)：
         x < -15.707963 或  -12.566371 < x < -9.424778 或  -6.283185 < x < -3.141593 或  0 < x < 3.141593 或  6.283185 < x < 9.424778 或  x ＞ 12.566371

---

    The final solution set is :
         x < -15.707963 或  -12.566371 < x < -9.424778 或  -6.283185 < x < -3.141593 或  0 < x < 3.141593 或  6.283185 < x < 9.424778 或  x ＞ 12.566371
