[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/(x+1)-1/(x-1) >2/x*x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / ( x + 1 ) - 1 / ( x - 1 ) >2 / x * x         (1)
        From the definition field of divisor
         x + 1 ≠ 0        (2 )
        From the definition field of divisor
         x - 1 ≠ 0        (3 )
        From the definition field of divisor
        x ≠ 0        (4 )

---

    From inequality(1)：
         -1 < x < 0 或  0 < x < 1
    From inequality(2)：
         x < -1 或  x ＞ -1
    From inequality(3)：
         x < 1 或  x ＞ 1
    From inequality(4)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         -1 < x < 0 或  0 < x < 1     (5)
    From inequalities (3) and (5)
         -1 < x < 0 或  0 < x < 1     (6)
    From inequalities (4) and (6)
         -1 < x < 0 或  0 < x < 0 或  0 < x < 1     (7)

---

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