    Assignment:Find the solution set of inequality tanx >4/7 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         tan x >4 / 7         (1)

    From inequality(1):
         x < -7.853982 或  -5.764039 < x < -4.712389 或  -2.622447 < x < -1.570796 或  0.519146 < x < 1.570796 或  3.660739 < x < 4.712389 或  x > 6.802331

    The final solution set is :

         x < -7.853982 或  -5.764039 < x < -4.712389 或  -2.622447 < x < -1.570796 或  0.519146 < x < 1.570796 或  3.660739 < x < 4.712389 或  x > 6.802331
