Correct Answer

A. (\0)

Step 1

Concept

Because \(\cos 0=1\) and \(0\in[0,\pi]\) so \(\cos^{-1}1=0\). For \(\cos^{-1}x\) the answer is not negative.

Step 2

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.

Step 3

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।
