WebWolfram Alpha's authoritative computational ability allows you to perform complex arithmetic, analyze and compute properties of complex functions and apply the methods … Web1 Answer. Claim: If F is a branch of the square root, then F′(z) = 1 2 ⋅ F(z). Proof: A holomorphic function F: U → C on some domain U ⊂ C is a branch of the square root if F(z)2 = z for all z ∈ U. Deriving this equation using the chain rule gives 2F(z)F′(z) = 1. . Why aren't we allowed to differentiate √z in the normal way and ...
