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

    From inequality(1)：
         4.712389 < x < 10.995574 或  10.995574 < x < 17.27876 或  17.27876 < x < 23.561945 或  23.561945 < x < 29.84513 或  29.84513 < x < 36.128316 或  36.128316 < x < 42.411501 或  42.411501 < x < 48.694686 或  48.694686 < x < 54.977871 或  x ＞ 54.977871
    From inequality(2)：
         x ＞ 0
    From inequality(3)：
         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
