[ 1/1Inequality]
    Assignment:Find the solution set of inequality sinx+cosx >5tan(x+1) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         sin x + cos x >5 * tan ( x + 1 )         (1)

    From inequality(1):
         x < -7.365841 或  -5.712389 < x < -4.094477 或  -2.570796 < x < -1.082656 或  0.570796 < x < 2.188709 或  3.712389 < x < 5.20053 或  x > 6.853982

    The final solution set is :

         x < -7.365841 或  -5.712389 < x < -4.094477 或  -2.570796 < x < -1.082656 或  0.570796 < x < 2.188709 或  3.712389 < x < 5.20053 或  x > 6.853982
