We say … WebTherefore, f satisfies the Cauchy-Riemann equations and has an antiderivative F. This antiderivative is necessarily of the form u+iv(x,y) for some x,y since ∂F ∂z = ∂F ∂x. So we have the equation ∂Ref ∂x +i ∂Imf ∂x = ux −iuy. So equating real parts, we get ux = ∂Re(F) ∂x. But the real part of this derivative of F is ∂u ...
