[ 1/1Inequality]
    Assignment:Find the solution set of inequality abs(1/sqrt(1+(200*3.14*x)^2)-1) <0.05 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         abs ( 1 / sqrt ( 1 + ( 200 * 3.14 * x ) ^ 2 ) - 1 ) <0.05         (1)
        From the definition field of √
         1 + ( 200 * 3.14 * x ) ^ 2 ≥ 0        (2 )

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
