[ 1/1Inequality]
Assignment:Find the solution set of inequality (3*sin(x)-6*cos(x)*sin(x)*sin(x))*(cos(x)+2*sin(x)-2)-(2*cos(x)-sin(x)*(3*sin(x)-2*sin(x)*sin(x)*sin(x))) = 00
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities:
( 3 * sin ( x ) - 6 * cos ( x ) * sin ( x ) * sin ( x ) ) * ( cos ( x ) + 2 * sin ( x ) - 2 ) - ( 2 * cos ( x ) - sin ( x ) * ( 3 * sin ( x ) - 2 * sin ( x ) * sin ( x ) * sin ( x ) ) ) 00 < x (1)
x <90 (2)
From inequality(1):
-4.712389 < x < -3.141593 或 0 < x < 0.643501 或 x > 1.570796
From inequality(2):
x < 90
From inequalities (1) and (2)
-4.712389 < x < -3.141593 或 0 < x < 0.643501 或 1.570796 < x < 90 (3)
The final solution set is :
-4.712389 < x < -3.141593 或 0 < x < 0.643501 或 1.570796 < x < 90 Your problem has not been solved here? Please take a look at the hot problems !
