Assignment:Find the solution set of inequality −5sin(6x)−30xcos(6x)+48x >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
-5 * sin ( 6 * x ) - 30 * x * cos ( 6 * x ) + 48 * x >0 (1)
From inequality(1):
-0.132193 < x < 0 或 x > 0.132193
The final solution set is :
-0.132193 < x < 0 或 x > 0.132193 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
