[ 1/1Inequality]
    Assignment:Find the solution set of inequality r*(1+r^0.5)^2/(r-1)^2 ≥0.99 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         r * ( 1 + r ^ 0.5 ) ^ 2 / ( r - 1 ) ^ 2 ≥0.99         (1)
        From the definition field of divisor
         x - 1 ≠ 0        (2 )

---

    From inequality(1)：
         r ≥ 0.248745
    From inequality(2)：
         r < 1 或  r ＞ 1

---

    From inequalities (1) and (2)
         0.248745 ≤ r < 1 或  r ＞ 1    (3)

---

    The final solution set is :
         0.248745 ≤ r < 1 或  r ＞ 1
