Derivative f’ of the function f(x)=exp x is: f’(x) = exp x for any value of x. Derivative of exponential x Derivative $f’$ of the function $f(x)=\exp x= e^{x}$ is: \(\forall x \in ]-\infty, +\infty[ , f'(x) = \exp x = e^{x}\) Proof/Demonstration \[\b...
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: \((\tan x)' =\lim _{h \rightarrow 0} \dfrac{\tan (x+h) - \tan x }{h}\)...
