[ 1/1Inequality]
    Assignment:Find the solution set of inequality (sinx+lnx+e3)/cosx >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( sin x + ln x + e 3 ) / cos x >0         (1)
        From the definition field of ln
        x > 0        (2 )

---

    From inequality(1)：
         0 < x < 1.570796 或  4.712389 < x < 7.853982 或  10.995574 < x < 14.137167 或  17.27876 < x < 20.420352 或  23.561945 < x < 26.703538
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0 < x < 1.570796 或  4.712389 < x < 7.853982 或  10.995574 < x < 14.137167 或  17.27876 < x < 20.420352 或  23.561945 < x < 26.703538     (3)

---

    The final solution set is :
         0 < x < 1.570796 或  4.712389 < x < 7.853982 或  10.995574 < x < 14.137167 或  17.27876 < x < 20.420352 或  23.561945 < x < 26.703538
