[ 1/1Inequality]
    Assignment:Find the solution set of inequality -sin(1)^2x^4-cos(111)x^3-tan(e)x^2-x-1 ) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -sin ( 1 ) ^ 2 * x ^ 4 - cos ( 111 ) * x ^ 3 - tan ( e x ^ 2 - x - 1 ) <0         (1)

---

    From inequality(1)：
         x < -0.524297 或  0 < x < 0.572662 或  0.795271 < x < 0.948096 或  x ＞ 1.04372

---

    The final solution set is :
         x < -0.524297 或  0 < x < 0.572662 或  0.795271 < x < 0.948096 或  x ＞ 1.04372
