Question:-
If Cosecθ = √5, find the value of:-
Solution:-
We have cosecθ = √5
From here we can find the value of sinθ
We know,
Hence,
We can write
Now,
Let us find cosθ in terms of sinθ.
We know,
Substituting the value of sinθ
=
By rationalising the denominator we get,
Now,
(i) 2 - sin²θ - cos²θ
⟶ Let us put the value of cosθ and sinθ.
=
(ii) 2 +
=
