Correct Answer

A. (\1)

Step 1

Concept

If \(\cos^{-1}x=0\), then \(x=\cos0=1\). In an inverse trigonometric equation apply the corresponding trigonometric function on both sides.

Step 2

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.

Step 3

Exam Tip

यदि \(\cos^{-1}x=0\) है तो \(x=\cos0=1\)। उल्टे त्रिकोणमितीय समीकरण में दोनों ओर संबंधित त्रिकोणमितीय फलन लगाएं।
