ZMap helps you visualize the graph of complex-valued functions. Such graphs are four-dimensional objects and cannot be shown easily, but with ZMap you can investigate how curves in a domain change as they are mapped by a complex function to its range.
You can enter an arbitrary complex function and choose from a number of preset curves to see how the function deforms them.
An introduction to the mathematics of complex numbers is included, as well as extensive online help and sample problems. ZMap is the perfect tool for anyone studying or interested in functions in the complex plane. It is particularly useful to determine mapping properties of complex functions.
ZMap runs as an applet or stand-alone program. Complete source code is available.
