\(\cot^{-1}\sqrt{3}\) का प्रधान मान क्या है?
What is the principal value of \(\cot^{-1}\sqrt{3}\)?
Explanation opens after your attempt
A. \(\frac{\pi}{6}\)
Concept
Because \(\cot\frac{\pi}{6}=\sqrt{3}\) and (\frac{\pi}{6}\in\(0,\pi\)). Remember (\(0,\pi\)) for the principal value of \(\cot^{-1}\).
Why this answer is correct
The correct answer is A. \(\frac{\pi}{6}\). Because \(\cot\frac{\pi}{6}=\sqrt{3}\) and (\frac{\pi}{6}\in\(0,\pi\)). Remember (\(0,\pi\)) for the principal value of \(\cot^{-1}\).
Exam Tip
क्योंकि \(\cot\frac{\pi}{6}=\sqrt{3}\) है और (\frac{\pi}{6}\in\(0,\pi\)) है। \(\cot^{-1}\) के प्रधान मान के लिए (\(0,\pi\)) याद रखें।
