[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/x*(ln(1/1-x)) <2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / x * ( ln ( 1 / 1 - x ) ) <2         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of ln
         1 / 1 - x > 0        (3 )

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x < 0 或  x ＞ 0
    From inequality(3)：
         x < 1

---

    From inequalities (1) and (2)
         x < 0 或  x ＞ 0    (4)
    From inequalities (3) and (4)
         x < 0 或  0 < x < 1     (5)

---

    The final solution set is :
         x < 0 或  0 < x < 1
