    Assignment:Find the solution set of inequality 2sin（x）cos（x） >sin（x） .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        2 * sin ( x ) * cos ( x ) > sin ( x )         (1)

---

    From inequality(1)：
         x < -7.330383 或  -6.283185 < x < -5.235988 或  -3.141593 < x < -1.047198 或  0 < x < 1.047198 或  3.141593 < x < 5.235988 或  x ＞ 6.283185

---

    The final solution set is :
         x < -7.330383 或  -6.283185 < x < -5.235988 或  -3.141593 < x < -1.047198 或  0 < x < 1.047198 或  3.141593 < x < 5.235988 或  x ＞ 6.283185
