The derivation steps and the reasons are:
-------- Addition
--------- Tangent sum identity
------- Simplify
The tangent sum identity states that:
To determine the derivation of tan(2x), we make use of the following steps.
Rewrite 2x as the addition of x and x.
So, we have:
--- step 1
Next, we apply the tangent sum identity.
Recall that:
Substitute x for a and b.
So, we have:
---- step 2
Simplify the denominator
Hence, the result of the derivation is
