\(\cos^{-1}x=0\) होने पर (x) का मान क्या है?
If \(\cos^{-1}x=0\), what is the value of (x)?
Explanation opens after your attempt
A. (\1)
Concept
If \(\cos^{-1}x=0\), then \(x=\cos0=1\). In an inverse trigonometric equation apply the corresponding trigonometric function on both sides.
Why this answer is correct
The correct answer is A. (\1). If \(\cos^{-1}x=0\), then \(x=\cos0=1\). In an inverse trigonometric equation apply the corresponding trigonometric function on both sides.
Exam Tip
यदि \(\cos^{-1}x=0\) है तो \(x=\cos0=1\)। उल्टे त्रिकोणमितीय समीकरण में दोनों ओर संबंधित त्रिकोणमितीय फलन लगाएं।
