[ 1/1Inequality]
    Assignment:Find the solution set of inequality 3sin（2x-2π/3） >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        3 * sin ( 2 * x - 2 * π / 3 ) >0         (1)

---

    From inequality(1)：
         x < -6.806784 或  -5.235988 < x < -3.665191 或  -2.094395 < x < -0.523599 或  1.047198 < x < 2.617994 或  4.18879 < x < 5.759587 或  x ＞ 7.330383

---

    The final solution set is :
         x < -6.806784 或  -5.235988 < x < -3.665191 或  -2.094395 < x < -0.523599 或  1.047198 < x < 2.617994 或  4.18879 < x < 5.759587 或  x ＞ 7.330383
