If `=sec^(2)theta+cos^(2)theta`, where `0ltthetalt(pi)/(2)`, then which one of the following is correct ?

A

`y = 0`

B

`0leyle2`

C

`yge2`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Since , `cos^(2)theta` lies between 0 and 1 therefore ,
`sec^(2)theta+cos^(2)thetage2,AA0lt(pi)/(2)`
`thereforeyge2`
