`sqrt(sqrt( 16 sin^4 theta + cosec^4 theta + 8) -4) =`

A

`2 sin theta-"cosec" theta `

B

`2 sin theta + "cosec " theta `

C

`2 " cosec " theta + cos theta `

D

`2 " cosec" theta+ sin theta `

Text Solution

Verified by Experts

The correct Answer is:
C
Use `a^(2)+b^(2)+2ab=(a+b)^(2) and sin theta. " cosec " theta =1`.
