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

---

    From inequality(1)：
         x ≥ 1/2
    From inequality(2)：
         x ≤ 0.79724
    From inequality(3)：
         x ≥ 0
    From inequality(4)：
         x ≤ 1

---

    From inequalities (1) and (2)
         1/2 ≤ x ≤ 0.79724    (5)
    From inequalities (3) and (5)
         1/2 ≤ x ≤ 0.79724    (6)
    From inequalities (4) and (6)
         1/2 ≤ x ≤ 0.79724    (7)

---

    The final solution set is :
         1/2 ≤ x ≤ 0.79724
