Answer 1

Answer:

please answer my question

Answer 2

Answer:

If u and v satisfy the Cauchy-Riemann equations, then f(z) has a complex derivative. The proof of this theorem is not difficult, but involves a more careful understanding of the meaning of the partial derivatives and linear approxi- mation in two variables. ∇v = (∂v ∂x , ∂v ∂y ) = ( − ∂u ∂y , ∂u ∂x ) .
