[ 1/1Inequality]
    Assignment:Find the solution set of inequality -2*sqrt(x*(1-x))+1     Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -2 * sqrt ( x * ( 1 - x ) ) + 1 < x + 1 / 3         (1)
        From the definition field of √
         x * ( 1 - x ) ≥ 0        (2 )

---

    From inequality(1)：
         x ＞ 0.091117
    From inequality(2)：
         0 ≤ x ≤ 1

---

    From inequalities (1) and (2)
         0.091117 < x ≤ 1     (3)

---

    The final solution set is :
         0.091117 < x ≤ 1
