Assignment:Find the solution set of inequality e^x(sinx+cosx)+1 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ^ x * ( sin x + cos x ) + 1 >0 (1)
From inequality(1):
x < 2.419166 或 5.494883 < x < 8.639505 或 11.780967 < x < 14.922565 或 18.064158 < x < 21.20575 或 24.347343 < x < 27.488936 或 x > 30.630528
The final solution set is :
x < 2.419166 或 5.494883 < x < 8.639505 或 11.780967 < x < 14.922565 或 18.064158 < x < 21.20575 或 24.347343 < x < 27.488936 或 x > 30.630528 *Note: Radian.Your problem has not been solved here? Please take a look at the hot problems !
