Jun 21, 2017 · $\begingroup$ The absolute value function has a derivative(s) on restricted domains. i.e. f'(x) = -1 for x <0 and f'(x) = 1 for x > 0. However, the absolute value function is not "smooth" at x = 0 so the derivative at that point does not exist. $\endgroup$ –

Apr 27, 2021 · And, when that happens, the derivative is indeed $\operatorname{sgn}(x)$ or $\frac x{|x|}$. But, since the derivative of the absolute value function is undefined at $0$, but $\operatorname{sgn}$ is defined at that point, those two functions have distinct domains and therefore they cannot possibly be equal.

Jul 24, 2021 · If you differentiate the absolute value function the result could be the Sign Function. By definition, the Sign Function is defined at 0, but there is no derivate of absolute value function at zero. So, the question is: Is the Sign Function a valid function to be the derivative of absolute value? Is there another function?

Oct 8, 2018 · The reason lies within “the limit definition of a derivative” I will jump to the explanation that sums it up since you have already stated f(x) at x=0 exists and there is continuity. The LIMIT of that “V” shape from the left MUST equal the …

Feb 24, 2015 · You can't do it without splitting the absolute value, so: If x>=0, than |x|=x and F(x)=intxdx=x^2/2+c. If x<0, than |x|=-x and F(x)=int-xdx=-x^2/2+c.
