प्रश्न
The domain of the function defined by f(x) = sin–1x + cosx is ______.
विकल्प
[–1, 1]
[–1, π + 1]
`(– oo, oo)`
φ
उत्तर
The domain of the function defined by f(x) = sin–1x + cosx is [–1, 1].
Explanation:
The domain of cos is R and the domain of sin–1 is [–1, 1].
Therefore, the domain of cosx + sin–1x is R ∩ [–1,1]
i.e., [–1, 1].
