ZMap is a Java applet that helps students visualize the graphs of complex-valued functions. Such graphs are four-dimensional objects and therefore can not be shown easily, but with ZMap students can investigate how curves in a domain change as they are mapped by a complex function to its range.
Note that ZMap requires the "Java Runtime Environment 1.4" or better. If you experience problems, visit www.javasoft.com to install or update the required software.
