Assignment:Find the solution set of inequality 3cos(x) >2(sin(x)^2) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
3 * cos ( x ) >2 * ( sin ( x ) ^ 2 ) (1)
From inequality(1):
-13.613568 < x < -11.519173 或 -7.330383 < x < -5.235988 或 -1.047198 < x < 1.047198 或 5.235988 < x < 7.330383 或 11.519173 < x < 13.613568
The final solution set is :
-13.613568 < x < -11.519173 或 -7.330383 < x < -5.235988 或 -1.047198 < x < 1.047198 或 5.235988 < x < 7.330383 或 11.519173 < x < 13.613568 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
