Hello :
<span>x-coordinates for the maximum points in the function f(x) = 4 cos(2x − π) from x = 0 to x = 2πis solutions of : f'(x) =0
f'(x) = - 2sin</span><span>(2x − π)
</span>- 2sin(2x − π) =0
sin (2x − π) =0
2x − π = kπ ... k in Z
x=(k+1)π/2....(general solutions in R)
<span>from x = 0 to x = 2π :
</span>k =0 : x = π/2
k=1 : x= π
k=2 : x= 3π/2
k = 3 : x=2π
Remains to be determined whether it is a maximum or minumum
-11, -6, -7 and -6.1 are the answers
The inequality is r lesser than or equal to -6
