Assignment:Find the solution set of inequality (5*sqrt3-14)*sinx+5*cosx+5 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 5 * sqrt 3 - 14 ) * sin x + 5 * cos x + 5 >0 (1)
From inequality(1):
-15.707963 < x < -11.061267 或 -9.424778 < x < -4.778082 或 -3.141593 < x < 1.505103 或 3.141593 < x < 7.788289 或 9.424778 < x < 14.071474
The final solution set is :
-15.707963 < x < -11.061267 或 -9.424778 < x < -4.778082 或 -3.141593 < x < 1.505103 或 3.141593 < x < 7.788289 或 9.424778 < x < 14.071474 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
