[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.7580 ≤0.4630cosx-0.2333√(1-cosx×cosx) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.7580 ≤0.4630 * cos x - 0.2333 * √ ( 1 - cos x × cos x )         (1)
        From the definition field of √
         1 - cos x × cos x ≥ 0        (2 )

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         x ≤ -4712389/500000 或  -4712389/500000 ≤ x ≤ -3141593/500000 或  -3141593/500000 ≤ x ≤ -3141593/500000 或  -3141593/500000 ≤ x ≤ -3141593/1000000 或  -3141593/1000000 ≤ x ≤ -3141593/1000000 或  -3141593/1000000 ≤ x ≤ 0 或  0 ≤ x ≤ 0 或  0 ≤ x ≤ 3141593/1000000 或  3141593/1000000 ≤ x ≤ 3141593/1000000 或  3141593/1000000 ≤ x ≤ 1256637/200000 或  x ≥ 1256637/200000

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
