    Assignment:Find the solution set of inequality t^2*lnt     Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         t ^ 2 * ln t < t ^ 2 - 1         (1)
        From the definition field of ln
        x > 0        (2 )

---

    From inequality(1)：
         1 < t < 2.218457
    From inequality(2)：
         t ＞ 0

---

    From inequalities (1) and (2)
         1 < t < 2.218457     (3)

---

    The final solution set is :
         1 < t < 2.218457
