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

---

    From inequality(1)：
         x < -0.618034
    From inequality(2)：
         x ≤ 2
    From inequality(3)：
         x ≥ -1

---

    From inequalities (1) and (2)
         x < -0.618034    (4)
    From inequalities (3) and (4)
         -1 ≤ x < -0.618034    (5)

---

    The final solution set is :
         -1 ≤ x < -0.618034
