Missbelladonna answer is correct
Given : sin θ + cos θ = m , and sec θ + cosec θ= n .
Exigency To Prove : n(m² – 1) = 2m . [ L.H.S = R.H.S ]
⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀
⠀⠀⠀Given that ,
⠀⠀⠀⠀⠀⠀▪︎⠀
⠀⠀⠀⠀⠀⠀▪︎⠀
⠀⠀⠀Need To Proove :
⠀⠀⠀⠀⠀⠀▪︎⠀
⠀⠀Here ,

⠀⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀⠀
⠀⠀⠀▪︎⠀
⠀⠀⠀▪︎⠀
⠀⠀⠀⠀⠀AND ,
⠀⠀⠀▪︎⠀
⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀
⠀⠀As , We can see that here , [ L.H.S = R.H.S ]
