(\tan\(\tan^{-1}x\)) किसके बराबर है जब \(x\in\mathbb{R}\)?
What is (\tan\(\tan^{-1}x\)) equal to when \(x\in\mathbb{R}\)?
Explanation opens after your attempt
A. \(\x\)
Concept
The domain of \(\tan^{-1}x\) is \(\mathbb{R}\) and (\tan\(\tan^{-1}x\)=x). This is a very common identity.
Why this answer is correct
The correct answer is A. \(\x\). The domain of \(\tan^{-1}x\) is \(\mathbb{R}\) and (\tan\(\tan^{-1}x\)=x). This is a very common identity.
Exam Tip
\(\tan^{-1}x\) का डोमेन \(\mathbb{R}\) है और (\tan\(\tan^{-1}x\)=x)। यह सबसे अधिक पूछी जाने वाली पहचान है।
