    Assignment:Find the solution set of inequality sqrt(2+2t) >-10/t .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sqrt ( 2 + 2 * t ) > -10 / t         (1)
        From the definition field of √
         2 + 2 * x ≥ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         t ＞ 0
    From inequality(2)：
         t ≥ -1
    From inequality(3)：
         t < 0 或  t ＞ 0

---

    From inequalities (1) and (2)
         t ＞ 0    (4)
    From inequalities (3) and (4)
         t ＞ 0    (5)

---

    The final solution set is :
         t ＞ 0
