Which of the following is correct?

A

`sin1^@gt sin1`

B

`sin1^@ltsin1`

C

`sin1^@=sin1`

D

`sin1^@=pi/180sin1`

Text Solution

Verified by Experts

The correct Answer is:
B
Since f(x) =sin x is an invreasing function for `0 ltx ltpi//2` and 1 rad is approximately `57^@` , we have
`1^@lt1^RrArr sin1^@,sin1`
