Final Answer

$\sec\left(x+1\right)^2$

Step-by-step explanation

Problem to solve:

$\frac{d}{dx}\left(\tan\left(x+1\right)\right)$

Choose the solving method

1

The derivative of the tangent of a function is equal to secant squared of that function times the derivative of that function, in other words, if ${f(x) = tan(x)}$, then ${f'(x) = sec^2(x)\cdot D_x(x)}$

$\sec\left(x+1\right)^2\frac{d}{dx}\left(x+1\right)$
2

The derivative of a sum of two functions is the sum of the derivatives of each function

$\sec\left(x+1\right)^2\left(\frac{d}{dx}\left(x\right)+\frac{d}{dx}\left(1\right)\right)$
3

The derivative of the constant function ($1$) is equal to zero

$\sec\left(x+1\right)^2\frac{d}{dx}\left(x\right)$
4

The derivative of the linear function is equal to $1$

$\sec\left(x+1\right)^2$

Final Answer

$\sec\left(x+1\right)^2$
$\frac{d}{dx}\left(\tan\left(x+1\right)\right)$
