If 0 lt x lt pi/2 then...

If `0 lt x lt pi/2` then

A

`cos x gt 1 -(2x)/(pi)`

B

`cos x lt -(2x)/(pi)`

C

`cos x gt (2x)/(pi)`

D

`cos x lt (2x)/(x)`

Text Solution

Verified by Experts

The correct Answer is:
A
If is evident from the graphs of the functions
`y= cos x and y = 1-(2x)/(pi )` that
` cos x gt 1 -(2x)/(pi)`
