[ 1/1Inequality]
    Assignment:Find the solution set of inequality sinxcosx+sin2xcosx+x ≤1.96 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sin x * cos x + sin 2 * x * cos x + x ≤1.96         (1)

---

    From inequality(1)：
         x ≤ 3.946973 或  8.770393 ≤ x ≤ 9.825924 或  15.347223 ≤ x ≤ 15.916558

---

    The final solution set is :
         x ≤ 3.946973 或  8.770393 ≤ x ≤ 9.825924 或  15.347223 ≤ x ≤ 15.916558
