WebTheorem 2.1: A differentiable function is continuous: If f(x)isdifferentiableatx = a,thenf(x)isalsocontinuousatx = a. Proof: Since f is differentiable at a, f(a)=lim x→a f(x)−f(a) x−a exists. Then lim x→a (f(x)−f(a)) = lim x→a (x−a)· f(x)−f(a) x−a This is okay because x−a =0forlimitat a. =lim x→a (x−a)lim x→a ... WebAug 3, 2024 · To fully understand a function's differentiability, here are some examples: Example 1 ...

WebYes, you can define the derivative at any point of the function in a piecewise manner. If f (x) is not differentiable at x₀, then you can find f' (x) for x < x₀ (the left piece) and f' (x) for x > x₀ (the right piece). f' (x) is not defined at x = x₀. WebApr 30, 2024 · Example 7.1.1. Consider the function f(z) = z ∗. According to the formula for the complex derivative, But if we plug in a real δz, we get a different result than if we plug in an imaginary δz: δz ∈ R ⇒ δz ∗ δz = 1. δz ∈ i ⋅ R ⇒ δz ∗ δz = − 1. We can deal with this complication by regarding the complex derivative as ...
