    Assignment:Find the solution set of inequality tanx ≥√3/3 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         tan x ≥ √ 3 / 3         (1)

---

    From inequality(1)：
         x ≤ -7.853982 或  -5.759587 ≤ x ≤ -4.712389 或  -2.617994 ≤ x ≤ -1.570796 或  0.523599 ≤ x ≤ 1.570796 或  3.665191 ≤ x ≤ 4.712389 或  x ≥ 6.806784

---

    The final solution set is :
         x ≤ -7.853982 或  -5.759587 ≤ x ≤ -4.712389 或  -2.617994 ≤ x ≤ -1.570796 或  0.523599 ≤ x ≤ 1.570796 或  3.665191 ≤ x ≤ 4.712389 或  x ≥ 6.806784
