[ 1/1Inequality]
    Assignment:Find the solution set of inequality √cosx ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         √ cos x ≥0         (1)

---

    From inequality(1)：
         -26.703538 ≤ x ≤ -20.420352 或  -20.420352 ≤ x ≤ -14.137167 或  -14.137167 ≤ x ≤ -7.853982 或  -7.853982 ≤ x ≤ -1.570796 或  -1.570796 ≤ x ≤ 4.712389 或  4.712389 ≤ x ≤ 10.995574 或  10.995574 ≤ x ≤ 17.27876 或  17.27876 ≤ x ≤ 23.561945 或  23.561945 ≤ x ≤ 29.84513 或  x ≥ 29.84513

    The final solution set is :
         -26.703538 ≤ x ≤ -20.420352 或  -20.420352 ≤ x ≤ -14.137167 或  -14.137167 ≤ x ≤ -7.853982 或  -7.853982 ≤ x ≤ -1.570796 或  -1.570796 ≤ x ≤ 4.712389 或  4.712389 ≤ x ≤ 10.995574 或  10.995574 ≤ x ≤ 17.27876 或  17.27876 ≤ x ≤ 23.561945 或  23.561945 ≤ x ≤ 29.84513 或  x ≥ 29.84513
