hammer [34]

The derivation steps and the reasons are:

$\tan(2x) = \tan(x+x)$ -------- Addition
$\tan(2x) = \frac{\tan(x) + \tan(x)}{1 - \tan(x) \tan(x)}$ --------- Tangent sum identity
$\tan(2x) = \frac{\tan(x) + \tan(x)}{1 - \tan^2(x)}$ ------- Simplify

<h3>What is the tangent sum identity?</h3>

The tangent sum identity states that:

$\tan(a + b) = \frac{\tan(a) + \tan(b)}{1 - \tan(a) \tan(b)}$

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:

$\tan(2x) = \tan(x+x)$ --- step 1

Next, we apply the tangent sum identity.

Recall that:

$\tan(a + b) = \frac{\tan(a) + \tan(b)}{1 - \tan(a) \tan(b)}$

Substitute x for a and b.

So, we have:

$\tan(2x) = \frac{\tan(x) + \tan(x)}{1 - \tan(x) \tan(x)}$ ---- step 2

Simplify the denominator

$\tan(2x) = \frac{\tan(x) + \tan(x)}{1 - \tan^2(x)}$

Hence, the result of the derivation is $\tan(2x) = \frac{\tan(x) + \tan(x)}{1 - \tan^2(x)}$

shutvik [7]

Answer: i'm not really sure how to answer this one but i think you're wanting an answer to something. the equation for it would be 5 + 5x meaning the 5 is already there, and x is for the minutes that are they filling it up. so if the question asks how much after 5 minutes, you simply just put the 5 in place for the x.
