Question :
Solution :
From the above equation, we get :
Method (I) :
By solving the LHS, we get :
We know that, tan(x) = sin(x)/cos(x), so by substituting it in the equation, we get :
Hence,
Thus,
[Proved]
Method (II) :
By solving the RHS, we get :
By substituting tan(x) = sin(x)/cos(x) in the equation, we get :
Thus,
