Web13 mei 2024 · This amounts to integrating to get f ( z) = ∫ z = x, y = 0 f ′ ( z) d z, where the f ′ ( z) is obtained by the formula I gave with the partial derivatives. Note that the integrand is evaluated along z = x and y = 0. Example: Let u ( x, y) = x 2 − y 2 so we find an analytic f ( z) such that ℜ f ( z) = u ( x, y). WebIf xxyyzz=c, then ∂ z/∂ x= Login.
