[ 1/1Inequality]
    Assignment:Find the solution set of inequality abs(ex-1-x-1/2x^2-1/6x^3) <1/99 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         abs ( e x - 1 - x - 1 / 2 * x ^ 2 - 1 / 6 * x ^ 3 ) <1 / 99         (1)

---

    From inequality(1)：
         -√923439/√1750000 < x < 0.677248

---

    The final solution set is :
         -√923439/√1750000 < x < 0.677248
