(\tan^{-1}(-x)) किसके बराबर है जब \(x\in\mathbb{R}\)?
What is (\tan^{-1}(-x)) equal to when \(x\in\mathbb{R}\)?
Explanation opens after your attempt
A. \(-\tan^{-1}x\)
Concept
The function \(\tan^{-1}x\) is odd, so (\tan^{-1}(-x)=-\tan^{-1}x). Keep the answer in the principal range.
Why this answer is correct
The correct answer is A. \(-\tan^{-1}x\). The function \(\tan^{-1}x\) is odd, so (\tan^{-1}(-x)=-\tan^{-1}x). Keep the answer in the principal range.
Exam Tip
\(\tan^{-1}x\) विषम फलन है इसलिए (\tan^{-1}(-x)=-\tan^{-1}x)। उत्तर हमेशा प्रधान सीमा में रखें।
