\(\cot^{-1}x\) की सामान्य प्रधान मान सीमा क्या ली जाती है?
What is the usual principal value range of \(\cot^{-1}x\)?
Explanation opens after your attempt
A. अंतराल (\(0,\pi\))Interval (\(0,\pi\))
Concept
The principal value of \(\cot^{-1}x\) is usually taken in (\(0,\pi\)). Hence \(\cot^{-1}0=\frac{\pi}{2}\).
Why this answer is correct
The correct answer is A. अंतराल (\(0,\pi\)) / Interval (\(0,\pi\)). The principal value of \(\cot^{-1}x\) is usually taken in (\(0,\pi\)). Hence \(\cot^{-1}0=\frac{\pi}{2}\).
Exam Tip
\(\cot^{-1}x\) का प्रधान मान प्रायः (\(0,\pi\)) में लिया जाता है। इस कारण \(\cot^{-1}0=\frac{\pi}{2}\) होता है।
