[ 1/1Inequality]
    Assignment:Find the solution set of inequality 391.3×10^6 ≤360×64000000×(0.78×400＋350×sin0.785/0.785) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        391.3 × 10 ^ 6 ≤360 × 64000000 × ( 0.78 × 400 + 350 × sin 0.785 / 0.785 )         (1)

---

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

---

    The final solution set is :
          ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
