    Assignment:Find the solution set of inequality 1+x+1/2*(x^2)+1/6*(x^3)+1/24*(x^4) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 + x + 1 / 2 * ( x ^ 2 ) + 1 / 6 * ( x ^ 3 ) + 1 / 24 * ( x ^ 4 ) <1         (1)

---

    From inequality(1)：
         -2.785294 < x < 0

---

    The final solution set is :
         -2.785294 < x < 0
