[ 1/1Inequality]
    Assignment:Find the solution set of inequality 100*sqrt（1-v^2） >434*(v^-1-v) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        100 * sqrt ( 1 - v ^ 2 ) >434 * ( v ^ -1 - v )         (1)
        From the definition field of √
         1 - x ^ 2 ≥ 0        (2 )

---

    From inequality(1)：
         -1 < v < 0
    From inequality(2)：
         -1 ≤ v ≤ 1

---

    From inequalities (1) and (2)
         -1 < v < 0     (3)

---

    The final solution set is :
         -1 < v < 0
