(\sin^{-1}(-x)) किसके बराबर है जब \(x\in[-1,1]\)?
What is (\sin^{-1}(-x)) equal to when \(x\in[-1,1]\)?
Explanation opens after your attempt
A. \(-\sin^{-1}x\)
Concept
The function \(\sin^{-1}x\) is odd, so (\sin^{-1}(-x)=-\sin^{-1}x). This identity is useful in sign-change questions.
Why this answer is correct
The correct answer is A. \(-\sin^{-1}x\). The function \(\sin^{-1}x\) is odd, so (\sin^{-1}(-x)=-\sin^{-1}x). This identity is useful in sign-change questions.
Exam Tip
\(\sin^{-1}x\) विषम फलन है इसलिए (\sin^{-1}(-x)=-\sin^{-1}x)। चिन्ह बदलने वाले प्रश्नों में यह पहचान उपयोगी है।
