\(\cos^{-1}x\) की सीमा से कौन सा मान संभव नहीं है?
Which value is not possible from the range of \(\cos^{-1}x\)?
Explanation opens after your attempt
A. \(-\frac{\pi}{3}\)
Concept
The range of \(\cos^{-1}x\) is \([0,\pi]\), so a negative value is not possible. In such questions check only the output range.
Why this answer is correct
The correct answer is A. \(-\frac{\pi}{3}\). The range of \(\cos^{-1}x\) is \([0,\pi]\), so a negative value is not possible. In such questions check only the output range.
Exam Tip
\(\cos^{-1}x\) की सीमा \([0,\pi]\) है इसलिए ऋणात्मक मान संभव नहीं है। ऐसे प्रश्नों में केवल आउटपुट रेंज देखें।
