Find all possible values of the parameter ' b ' for which the function,
`f(x)=sin 2x-8(b+2)cos x - (4b^(2)+16b+6)x`
is monotonic decreasing throughout the number line and has no critical points.

Text Solution

Verified by Experts

The correct Answer is:
Hence `b in (-oo, - (3+sqrt(3)))uu (sqrt(3)-1, oo)`
