Derivative $f’$ of function $f(x)=\arctan{x}$ is: \(\forall x \in \mathbb{R} ,\quad f'(x) = \dfrac{1}{1+x^2}\) Proof Remember that function $\arctan$ is the inverse function of $\tan$ : \[\left(f^{-1} \circ f\right)=\left(\tan \circ \arctan\right)(x)=\...
Derivative of tan x Derivative $f’$ of the function $f(x)=\tan x$ is: \(\forall x \neq \frac{\pi}{2}+k\pi, k \in \mathbb{Z}, f'(x) = 1+\tan ^{2} x\) Proof First we have: \((\tan x)' =\lim _{h \rightarrow 0} \dfrac{\tan (x+h) - \tan x }{h}\)...
