This Demonstration illustrates that functions in a real two-dimensional vector space are equivalent to functions in the field of complex numbers. Specifically, we consider a class of functions of the form , where and are different integers. The black arrow traces out the function , shown as a black curve, while the two component vectors are represented by red and blue arrows, tracing out red and blue circles.
