      4.2.4 Derivative . Definition 4.8 The derivative of a complex function f at a point written . is defined by = Provided that this limit exists. In this case, we say f is differentiable at . If we write , we also have = . Example 16 Show that f (z) = is differentiable for all complex numbers and = 2z. Solution Let be any complex number. = = .

      We can define complex valued functions of a complex variable. That is, the domain of the function is the complex variable field and the range is also the complex field. We can write this as . w = f(z) where both w and z are complex numbers. Such functions have complex numbers as parameters, as well. For example, we can write the following function
