[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1/2 <= sin(alpha)/2-cos(alpha)/5+2556945619965371/18014398509481984 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 / 2 <= sin ( alpha ) / 2 - cos ( alpha ) / 5 + 2556945619965371 / 18014398509481984         (1)

---

    From inequality(1)：
         alpha ≤ -16.05482 或  -11.458501 ≤ alpha ≤ -9.771635 或  -5.175316 ≤ alpha ≤ -3.48845 或  1.10787 ≤ alpha ≤ 2.794736 或  7.391055 ≤ alpha ≤ 9.077921 或  alpha ≥ 13.67424

---

    The final solution set is :
         alpha ≤ -16.05482 或  -11.458501 ≤ alpha ≤ -9.771635 或  -5.175316 ≤ alpha ≤ -3.48845 或  1.10787 ≤ alpha ≤ 2.794736 或  7.391055 ≤ alpha ≤ 9.077921 或  alpha ≥ 13.67424
