    Assignment:Find the solution set of inequality -sinx-cosx-1 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -sin x - cos x - 1 >0         (1)

---

    From inequality(1)：
         x < -14.137167 或  -9.424778 < x < -7.853982 或  -3.141593 < x < -1.570796 或  3.141593 < x < 4.712389 或  9.424778 < x < 10.995574 或  x ＞ 15.707963

---

    The final solution set is :
         x < -14.137167 或  -9.424778 < x < -7.853982 或  -3.141593 < x < -1.570796 或  3.141593 < x < 4.712389 或  9.424778 < x < 10.995574 或  x ＞ 15.707963
