need solution for RD Sharma maths class 12 chapter Inverse Trignometric Functions exercise 3.7 question 2 sub question (v)

Answers (1)

Answer: 3

Hint: The principal value branch of function $\cos ^{-1}$ is $\left [ 0,\pi \right ]$
Given: $\cos ^{-1}(\cos 3)$

Explanation:

We know that

$\cos ^{-1}(\cos 3)=3,3 \in[0, \pi] \quad\left[\cos ^{-1}(\cos \theta)=\theta \text { if } 0 \leq \theta \leq \pi\right]$

Hence, the answer is $\cos ^{-1}(\cos 3)=3$
