Assignment:Find the solution set of inequality 3cosx-√3sinx >√3 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
3 * cos x - √ 3 * sin x > √ 3 (1)
From inequality(1):
-14.137167 < x < -12.042772 或 -7.853982 < x < -5.759587 或 -1.570796 < x < 0.523599 或 4.712389 < x < 6.806784 或 10.995574 < x < 13.089969
The final solution set is :
-14.137167 < x < -12.042772 或 -7.853982 < x < -5.759587 或 -1.570796 < x < 0.523599 或 4.712389 < x < 6.806784 或 10.995574 < x < 13.089969 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
