Find the values of each of the following:

Question

Philoid · Accepted Answer

We will solve this problem by expressing sin2θ and cos2θ in terms of tanθ

Now let us put, x = tanθ. Then we will have,

θ = tan^-1x

Now again, Let’s put, y = tan∅. Then we will have,

∅ = tan^-1y

Now,

Hence, the value of
