[ 1/1Inequality]
    Assignment:Find the solution set of inequality （sinx）^3-3xx+sqrt(2x)+abs(x) <= 10 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( sin x ) ^ 3 - 3 * x * x + sqrt ( 2 * x ) + abs ( x ) <= 10         (1)
        From the definition field of √
         2 * x ≥ 0        (2 )

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x ≥ 0

---

    From inequalities (1) and (2)
         x ≥ 0    (3)

---

    The final solution set is :
         x ≥ 0
