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

---

    From inequality(1)：
         x < 0.179521 或  0.33166 < x < 0.456273 或  0.555107 < x < 0.635525 或  0.852344 < x < 0.955393 或  x ＞ 1.122577
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0 < x < 0.179521 或  0.33166 < x < 0.456273 或  0.555107 < x < 0.635525 或  0.852344 < x < 0.955393 或  x ＞ 1.122577    (3)

---

    The final solution set is :
         0 < x < 0.179521 或  0.33166 < x < 0.456273 或  0.555107 < x < 0.635525 或  0.852344 < x < 0.955393 或  x ＞ 1.122577
