When we consider the derivative of a complex function, using the usual definition of a derivative from the first course in calculus, we have the following result. [48] Since z represents a two-dimensional space (containing both the x and y directions) we may have different definitions of this derivative depending on the directions in which we ...

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

Derivative of a function ... Use the chain rule to find derivatives of complex functions. Vocabulary: none new. Key Concept: Differentiating a Composite Function: If David can type twice as fast as Mary and Mary can type three times as fast as Joe, then David can type 2•3=6 times as fast as Joe. This is basically the Chain Rule.

The derivative of a complex valued function, φ(ς)=f(u,v)+i g(u,v) , where ς = u + i v ε C and f and g are real functions, exists if the partial are continuous and satisfy both fu = gv & fv = -gu. The pair of partial differential equation are known as the Cauchy-Riemann equations. Thus, if the function satisfies the Cauchy-Riemann equations ...
