    Assignment:Find the solution set of inequality tan(180-2x) >0.5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         tan ( 180 - 2 * x ) >0.5         (1)

---

    From inequality(1)：
         -3.462381 < x < -2.908807 或  -1.891585 < x < -1.338011 或  -0.320789 < x < 0.232786 或  1.250008 < x < 1.803582 或  2.820804 < x < 3.374378

---

    The final solution set is :
         -3.462381 < x < -2.908807 或  -1.891585 < x < -1.338011 或  -0.320789 < x < 0.232786 或  1.250008 < x < 1.803582 或  2.820804 < x < 3.374378
