    Assignment:Find the solution set of inequality tan(x) >-0.5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         tan ( x ) > -0.5         (1)

---

    From inequality(1)：
         -6.746833 < x < -4.712389 或  -3.60524 < x < -1.570796 或  -0.463648 < x < 1.570796 或  2.677945 < x < 4.712389 或  5.819538 < x < 7.853982

---

    The final solution set is :
         -6.746833 < x < -4.712389 或  -3.60524 < x < -1.570796 或  -0.463648 < x < 1.570796 或  2.677945 < x < 4.712389 或  5.819538 < x < 7.853982
