The set of values of x for which tan1x1x2=sin1x holds,

a
R
b
(-1, 1)
c
[0, 1]
d
[-1, 0]

detailed solution

Correct option is B

We observe that RHS is defined for all x∈[−1, 1]whereas LHS is meaningful for -1 < x < l.Also, for x∈(−1, 1), we havetan−1⁡x1−x2=tan−1⁡sin⁡θcos⁡θ, where x=sin⁡θ=θ=sin−1⁡x
