Question

Q. let ( f(x)=sin left(frac{pi}{6} sin left(frac{pi}{2} sin nright)right) ) for all ( x in R ). Then
the range of ( f^{6}(n) ) is
Ans ( rightarrow ) we know the ramge of sinn is from [-1,1]
Homee Range of ( f(u) ) is [-0.5,0.5]
option 3 is correct answer

# 54 et f(x) = sin "sin sin x) for all xer. Then the range of f(x), is (1) (-0.25, 0.5) (2) (-1, 1) (3) (-0.5, 0.5) (4) (-0.25, 0.25)
