I tried the Jensen Inequality and calculus, but, wasn't good.

You were asked to please show your work. Possibly the work you did was logically correct but you made an error in your work. This is now the 2nd time you are being asked to show your work. Please do this so we can give you the best help we can. Thanks.

I did [MATH]f(x)=\sin^{\sin(x)}(x)-\cos(x)[/MATH] and I calculate [MATH]f'(x)[/MATH], but wasn't good.

No, you did not. You were asked twice to show your work. Doing work at home or saying that you did work at home does not help us help you if you refuse to show us your work. Me personally, I am out of here.
