Assignment:Find the solution set of inequality √3sin(y)−cos(y) >1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
√ 3 * sin ( y ) - cos ( y ) >1 (1)
From inequality(1):
y < -15.707963 或 -11.519173 < y < -9.424778 或 -5.235988 < y < -3.141593 或 1.047198 < y < 3.141593 或 7.330383 < y < 9.424778 或 y > 13.613568
The final solution set is :
y < -15.707963 或 -11.519173 < y < -9.424778 或 -5.235988 < y < -3.141593 或 1.047198 < y < 3.141593 或 7.330383 < y < 9.424778 或 y > 13.613568 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
