    Assignment:Find the solution set of inequality sinx+x^3lnx >2cosxe^x .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sin x + x ^ 3 * ln x >2 * cos x * e ^ x         (1)
        From the definition field of ln
        x > 0        (2 )

    From inequality(1)：
         1.34742 < x < 5.362556 或  7.633138 < x < 11.021824 或  14.134448 < x < 17.27899 或  20.420335 < x < 23.561946 或  26.703537 < x < 29.84513
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         1.34742 < x < 5.362556 或  7.633138 < x < 11.021824 或  14.134448 < x < 17.27899 或  20.420335 < x < 23.561946 或  26.703537 < x < 29.84513     (3)

---

    The final solution set is :
         1.34742 < x < 5.362556 或  7.633138 < x < 11.021824 或  14.134448 < x < 17.27899 或  20.420335 < x < 23.561946 或  26.703537 < x < 29.84513
