If x = sin^(-1)(sin 10) and y = cos^(-1)...

If `x = sin^(-1)(sin 10) and y = cos^(-1)(cos 10)` then `y - x` is equal to:

A

10

B

`pi`

C

18

D

0

Verified by Experts

The correct Answer is:

B

`x=sin^(-1)(sin10) and y=cos^(-1)(cos10)`
`x=sin^(-1)(sin10)=3pi-10`
`y=cos^(-1)(cos10)=4pi-10`
`y-x=pi`
