[ 1/1Inequality]
    Assignment:Find the solution set of inequality x*(4-(sqrt(0.09-x*x)-x))/sqrt(0.09-x*x) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * ( 4 - ( sqrt ( 0.09 - x * x ) - x ) ) / sqrt ( 0.09 - x * x ) <1         (1)
        From the definition field of √
         0.09 - x * x ≥ 0        (2 )
        From the definition field of √
         0.09 - x * x ≥ 0        (3 )

---

    From inequality(1)：
         -0.3 < x < 0.076602
    From inequality(2)：
         -3/10 ≤ x ≤ 3/10
    From inequality(3)：
         -3/10 ≤ x ≤ 3/10

---

    From inequalities (1) and (2)
         -0.3 < x < 0.076602     (4)
    From inequalities (3) and (4)
         -0.3 < x < 0.076602     (5)

---

    The final solution set is :
         -0.3 < x < 0.076602
