    Assignment:Find the solution set of inequality 928*cosx+1950*sinx ≤1090 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        928 * cos x + 1950 * sin x ≤1090         (1)

---

    From inequality(1)：
         -16.681217 ≤ x ≤ -12.481478 或  -10.398031 ≤ x ≤ -6.198293 或  -4.114846 ≤ x ≤ 0.084893 或  2.168339 ≤ x ≤ 6.368078 或  8.451525 ≤ x ≤ 12.651263

---

    The final solution set is :
         -16.681217 ≤ x ≤ -12.481478 或  -10.398031 ≤ x ≤ -6.198293 或  -4.114846 ≤ x ≤ 0.084893 或  2.168339 ≤ x ≤ 6.368078 或  8.451525 ≤ x ≤ 12.651263
