21 cze 2017 · The instructor highlighted that the absolute value function does not have a derivative compared to $f(x) = x|x|$. If I would to apply the power rule: $f(x) = nx^{n-1}$, where $f(0) = 1*0^{1-1}$. Because 0 to the power of 0 is undefined.

14 sie 2015 · To elaborate on Dr. MV's answer, we can find the derivative of the absolute value function by noting $$ |x|=\sqrt{x^2}$$ and then using the chain rule. The proof goes: $$ \frac d{dx} \sqrt{x^2}=\frac1{2\sqrt{x^2}}\cdot \frac{d}{dx}x^2=\frac{2x}{2\sqrt{x^2}}=\frac{x}{|x|}$$
19 kwi 2021 · Let $\size x$ be the absolute value of $x$ for real $x$. Then: $\dfrac \d {\d x} \size x = \dfrac x {\size x}$ for $x \ne 0$. At $x = 0$, $\size x$ is not differentiable. Corollary. Let $u$ be a differentiable real function of $x$. Then: $\dfrac \d {\d x} \size u = \dfrac u {\size u} \dfrac {\d u} {\d x}$ for $u \ne 0$.
