\(\cos^{-1}1\) का मान क्या है?
What is the value of \(\cos^{-1}1\)?
Explanation opens after your attempt
A. (\0)
Concept
Because \(\cos 0=1\) and \(0\in[0,\pi]\) so \(\cos^{-1}1=0\). For \(\cos^{-1}x\) the answer is not negative.
Why this answer is correct
The correct answer is A. (\0). Because \(\cos 0=1\) and \(0\in[0,\pi]\) so \(\cos^{-1}1=0\). For \(\cos^{-1}x\) the answer is not negative.
Exam Tip
क्योंकि \(\cos 0=1\) और \(0\in[0,\pi]\) है इसलिए \(\cos^{-1}1=0\)। \(\cos^{-1}x\) में उत्तर ऋणात्मक नहीं होता।
