[ 1/1Inequality]
    Assignment:Find the solution set of inequality e-（（xπ）/sqrt（1-x^2）) <0.05 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         e -( ( x * π ) / sqrt ( 1 - x ^ 2 ) ) <0.05         (1)
        From the definition field of √
         1 - x ^ 2 ≥ 0        (2 )

---

    From inequality(1)：
         x < -1 或  x ＞ 0.690107
    From inequality(2)：
         -1 ≤ x ≤ 1

---

    From inequalities (1) and (2)
         0.690107 < x ≤ 1     (3)

---

    The final solution set is :
         0.690107 < x ≤ 1
