    Assignment:Find the solution set of inequality 34 <(75+6.3cosx）-（36-6.3sinx）tanx .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        34 < ( 75 + 6.3 * cos x ) - ( 36 - 6.3 * sin x ) * tan x         (1)

---

    From inequality(1)：
         -7.853982 < x < -5.31722 或  -4.712389 < x < -2.407074 或  -1.570796 < x < 0.965966 或  1.570796 < x < 3.876112 或  4.712389 < x < 7.249151

---

    The final solution set is :
         -7.853982 < x < -5.31722 或  -4.712389 < x < -2.407074 或  -1.570796 < x < 0.965966 或  1.570796 < x < 3.876112 或  4.712389 < x < 7.249151
