The number of real solutions (x, y), where ` |y|= sin x , y= cos^(-1)(cos x), -2pi le x le 2pi `, is :

A

2

B

1

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
C
Graph of |y| =sin x and y = `cos^(-1)` are shown in fig 19 it is evident form the graph that the curves inersect at `(0,0) (2,pi,0)` and `(-2pi,0)` hence there are 3 solution
