Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 - 2 * cos x > sin x (1)
From inequality(1):
-17.922261 < x < -12.566371 或 -11.639075 < x < -6.283185 或 -5.35589 < x < 0 或 0.927295 < x < 6.283185 或 7.210481 < x < 12.566371
The final solution set is :
-17.922261 < x < -12.566371 或 -11.639075 < x < -6.283185 或 -5.35589 < x < 0 或 0.927295 < x < 6.283185 或 7.210481 < x < 12.566371 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
