Answer 2

Answer:

Solution :- Let , ∅ = @

Sec @ + tan @ = p

We know ,

Sec ²@ - tan ²@ = 1

Hence ,

Sec @ - tan @ = 1/p

______________________________________________________

Now , take both equations :-

2 sec @ = p + 1/p = ( p²+1 ) / p

:- Sec @ = ( p²+1 ) / 2p

:- cos @ = 2p / ( 1+p² )

Ans :- sin @ = ( 1-p² / 1+p² )
