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

---

    From inequality(1)：
         n < -1 或  n ＞ -2/3
    From inequality(2)：
         n < -1 或  -1 < n < 0 或  0 < n < 1 或  n ＞ 1
    From inequality(3)：
         n < 0 或  n ＞ 0

---

    From inequalities (1) and (2)
         n < -1 或  -2/3 < n < 0 或  0 < n < 1 或  n ＞ 1    (4)
    From inequalities (3) and (4)
         n < -1 或  -2/3 < n < 0 或  0 < n < 1 或  n ＞ 1    (5)

---

    The final solution set is :
         n < -1 或  -2/3 < n < 0 或  0 < n < 1 或  n ＞ 1
