Apply the quotient rule for differentiation, which states that if $f(x)$ and $g(x)$ are functions and $h(x)$ is the function defined by ${\displaystyle h(x) = \frac{f(x)}{g(x)}}$, where ${g(x) \neq 0}$, then ${\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}$

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

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

Learn how to solve problems step by step online. Find the derivative d/dx(tan(x)/(1+x)). Apply the quotient rule for differentiation, which states that if f(x) and g(x) are functions and h(x) is the function defined by {\displaystyle h(x) = \frac{f(x)}{g(x)}}, where {g(x) \neq 0}, then {\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}. 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)}. The derivative of the linear function is equal to 1. The derivative of a sum of two or more functions is the sum of the derivatives of each function.

##  Final answer to the problem

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