    Assignment:Find the solution set of inequality e^sint-cost-1 <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         e ^ sin t - cos t - 1 <0         (1)

---

    From inequality(1)：
         -14.734622 < t < -11.933644 或  -8.451436 < t < -5.650459 或  -2.168251 < t < 0.632727 或  4.114934 < t < 6.915912 或  10.398119 < t < 13.199097

---

    The final solution set is :
         -14.734622 < t < -11.933644 或  -8.451436 < t < -5.650459 或  -2.168251 < t < 0.632727 或  4.114934 < t < 6.915912 或  10.398119 < t < 13.199097
