Derivative of complex numbers
WebLet z = x+jy, for x,y real, denote a complex number and let f(z)=u(x,y)+jv(x,y) be a general complex-valued function of the complex number z.2 In standard complex variables courses it is emphasized that for the complex derivative, f (z) = lim Δz→0 f(z +Δz)−f(z) Δz, to exist in a meaningful way it must be independent of the direction with ...

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 ...
