Secθ+tanθ=p ----------------------(1) ∵, sec²θ-tan²θ=1 or, (secθ+tanθ)(secθ-tanθ)=1 or, secθ-tanθ=1/p ----------------(2) Adding (1) and (2) we get, 2secθ=p+1/p or, secθ=(p²+1)/2p ∴, cosθ=1/secθ=2p/(p²+1) ∴, sinθ=√(1-cos²θ) =√[1-{2p/(p²+1)}²] =√[1-4p²/(p²+1)²] =√[{(p²+1)²-4p²}/(p²+1)²] =√[(p⁴+2p²+1-4p²)/(p²+1)²] =√(p⁴-2p²+1)/(p²+1) =√(p²-1)²/(p²+1) =(p²-1)/(p²+1) ∴, cosecθ=1/sinθ=1/[(p²-1)/(p²+1)]=(p²+1)/(p²-1) I HOPE THIS HELPS!
