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

---

    From inequality(1)：
         0 < a < 0.443039
    From inequality(2)：
         a ＞ 0
    From inequality(3)：
         a < 0 或  a ＞ 0

---

    From inequalities (1) and (2)
         0 < a < 0.443039     (4)
    From inequalities (3) and (4)
         0 < a < 0.443039     (5)

---

    The final solution set is :
         0 < a < 0.443039
