[ 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):
         0.179521 < x < 0.33166 或  0.456273 < x < 0.555107 或  0.635525 < x < 0.702622 或  0.702622 < x < 0.852344 或  0.955393 < x < 1.031456 或  1.031456 < x < 1.122577
    From inequality(2):
         x > 0

    From inequalities (1) and (2)
         0.179521 < x < 0.33166 或  0.456273 < x < 0.555107 或  0.635525 < x < 0.702622 或  0.702622 < x < 0.852344 或  0.955393 < x < 1.031456 或  1.031456 < x < 1.122577     (3)

    The final solution set is :

         0.179521 < x < 0.33166 或  0.456273 < x < 0.555107 或  0.635525 < x < 0.702622 或  0.702622 < x < 0.852344 或  0.955393 < x < 1.031456 或  1.031456 < x < 1.122577
