    Assignment:Find the solution set of inequality lnx >(1/e)*x ) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ln x > ( 1 / e * x )         (1)
        From the definition field of ln
        x > 0        (2 )

---

    From inequality(1)：
         x < 0
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!    (3)

---

    The final solution set is :
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
