    Assignment:Find the solution set of inequality xsinx >5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * sin x >5         (1)

---

    From inequality(1)：
         x < -19.11422 或  -15.376776 < x < -12.962372 或  -8.822221 < x < -7.068891 或  7.068891 < x < 8.822221 或  12.962372 < x < 15.376776 或  x ＞ 19.11422

---

    The final solution set is :
         x < -19.11422 或  -15.376776 < x < -12.962372 或  -8.822221 < x < -7.068891 或  7.068891 < x < 8.822221 或  12.962372 < x < 15.376776 或  x ＞ 19.11422
