is used to prove the given equation.
Step-by-step explanation:
We have given an equation:

We will consider right hand side first
tan x can be written as:

So, on substituting tan x in the left hand side of the given equation we get:

Cancel common term from denominator and numerator which is cosx we get

And we have an identity:


Hence, right hand side is equal to
.
