Correct Answer

A. \(-\tan^{-1}x\)

Step 1

Concept

The function \(\tan^{-1}x\) is odd, so (\tan^{-1}(-x)=-\tan^{-1}x). Keep the answer in the principal range.

Step 2

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.

Step 3

Exam Tip

\(\tan^{-1}x\) विषम फलन है इसलिए (\tan^{-1}(-x)=-\tan^{-1}x)। उत्तर हमेशा प्रधान सीमा में रखें।
