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 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
