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

    From inequality(1):
         x < 0 或  0 < x < 1.696812
    From inequality(2):
         x > -1

    From inequalities (1) and (2)
         -1 < x < 0 或  0 < x < 1.696812     (3)

    The final solution set is :

         -1 < x < 0 或  0 < x < 1.696812
