[ 1/1Inequality]
    Assignment:Find the solution set of inequality e^(-3.14x/(1-x＾2)＾0.5) ≤0.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         e ^ ( -3.14 * x / ( 1 - x ^ 2 ) ^ 0.5 ) ≤0.2         (1)
        From the definition field of divisor
         1 - x ^ 2 ≠ 0        (2 )

---

    From inequality(1)：
         x ≥ 0.456133
    From inequality(2)：
         x < -1 或  -1 < x < 1 或  x ＞ 1

---

    From inequalities (1) and (2)
         0.456133 ≤ x < 1 或  x ＞ 1    (3)

---

    The final solution set is :
         0.456133 ≤ x < 1 或  x ＞ 1
