[ 1/1Inequality]
    Assignment:Find the solution set of inequality e^x(sinx+cosx)+1 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         e ^ x * ( sin x + cos x ) + 1 >0         (1)

    From inequality(1):
         x < 2.419166 或  5.494883 < x < 8.639505 或  11.780967 < x < 14.922565 或  18.064158 < x < 21.20575 或  24.347343 < x < 27.488936 或  x > 30.630528

    The final solution set is :

         x < 2.419166 或  5.494883 < x < 8.639505 或  11.780967 < x < 14.922565 或  18.064158 < x < 21.20575 或  24.347343 < x < 27.488936 或  x > 30.630528
