4 Answers. For x = 0 the function isn't differentiable. By using the chain rule. Your function is even and that means that it's derivative is odd function. Thus, for x > 0 we have that f ′ (x) = (√x) ′ = 1 2√x, while for x < 0, we have − f ′ (x) = f ′ ( − x) = 1 2√− x.where the vertical bars denote the absolute value.This is an example of the (ε, δ)-definition of limit.. If the function is differentiable at , that is if the limit exists, then this limit is called the derivative of at .Multiple notations for the derivative exist.

As Masacroso pointed out in his answer, for n = 1 n = 1 the second derivative of the absolute value function is 0 0 everywhere, except for x = 0 x = 0. Furthermore, for n = 1 n = 1 you can write x/|x| x / | x | as 2H(x) − 1 2 H ( x) − 1, in which H(x) H ( x) is the Heaviside function.Examples for. Derivatives.
