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

---

    From inequality(1)：
         x < -14.212923 或  -10.894333 < x < -7.997383 或  -4.415229 < x < -2.380741 或  0 < x < 1.065379 或  4.883194 < x < 7.739305 或  x ＞ 11.078461

---

    The final solution set is :
         x < -14.212923 或  -10.894333 < x < -7.997383 或  -4.415229 < x < -2.380741 或  0 < x < 1.065379 或  4.883194 < x < 7.739305 或  x ＞ 11.078461
