    Assignment:Find the solution set of inequality sinx+xtan(-3x^2) >8.11 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sin x + x * tan ( -3 * x ^ 2 ) >8.11         (1)

---

    From inequality(1)：
         -1.914469 < x < -1.896416 或  -0.723601 < x < -0.704861 或  0.723601 < x < 0.7463 或  1.914469 < x < 1.937287

---

    The final solution set is :
         -1.914469 < x < -1.896416 或  -0.723601 < x < -0.704861 或  0.723601 < x < 0.7463 或  1.914469 < x < 1.937287
