The derivative of a complex function is calculated by doing the simplifications step by step by applying the various differentiation rules, like the chain rule, product rule, quotient rule, power rule, and so on
Find the derivative of the function: f(x)=lnx2(x−3)3(x+1)4 logarithmic Differentiation: To find the derivative of a complex function by applying the law of the logarithm is known as logarithmic differentiation. The following rule of the logarithm is used to evalu...
The definition of the derivative formula is the change in the output of a function with respect to the input of a function. Over an interval on a function of length h, it is the limit of (f(x+h) - f(x))/h as h approaches 0. How do I find the derivative of a function?
In this chapter, you learned how to find a derivative using the definition of the derivative, a process that is very time-consuming and sometimes involves a lot of complex algebra. Fortunately , there's shortcut to taking derivatives, so you'll never have to use the definition again-except...
For example, textbook examples to the contrary, the "derivative" (read: complex derivative) of the absolute value function does not exist because at every point in the complex plane, the value of the derivative depends on the direction in which the derivative is taken (so the Cauchy-Riemann ...

Suppose that f = QeP where Q is a real rational function and P is a polynomial, not necessarily real, and that f has only real zeros. We prove that then P(z) = az2 + bz + c where a 0 and b is real, or f (z) = AeBz where A and B are nonzero complex constants.doi:...
learning why conformal doesn't necessarily mean differentiable, read Chapter 4.VI "Conformal = Analytic" of Tristan Needham's "Visual Complex Analysis", which you can find here: http://usf.usfca.edu/vca/ This book is incredible, some of the ideas in this video were taken from this book....
