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

---

    From inequality(1)：
         x ≥ 1/2
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
         x ≥ 1/2    (3)

---

    The final solution set is :
         x ≥ 1/2
