[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/sinx ≥1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / sin x ≥1         (1)

---

    From inequality(1)：
         x ≤ -9.424778 或  -6.283185 ≤ x ≤ -4712389/1000000 或  -4712389/1000000 ≤ x ≤ -4712389/1000000 或  -4712389/1000000 ≤ x ≤ -3.141593 或  0 ≤ x ≤ 1570797/1000000 或  1570797/1000000 ≤ x ≤ 1570797/1000000 或  1570797/1000000 ≤ x ≤ 3.141593 或  x ≥ 6.283185

    The final solution set is :
         x ≤ -9.424778 或  -6.283185 ≤ x ≤ -4712389/1000000 或  -4712389/1000000 ≤ x ≤ -4712389/1000000 或  -4712389/1000000 ≤ x ≤ -3.141593 或  0 ≤ x ≤ 1570797/1000000 或  1570797/1000000 ≤ x ≤ 1570797/1000000 或  1570797/1000000 ≤ x ≤ 3.141593 或  x ≥ 6.283185
