[ 1/1Inequality]
    Assignment:Find the solution set of inequality 10T^2/(1+T) >-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        10 * T ^ 2 / ( 1 + T ) > -1         (1)
        From the definition field of divisor
         1 + x ≠ 0        (2 )

---

    From inequality(1)：
         T ＞ -1
    From inequality(2)：
         T < -1 或  T ＞ -1

---

    From inequalities (1) and (2)
         T ＞ -1    (3)

---

    The final solution set is :
         T ＞ -1
