Domain coloring

In complex analysis, domain coloring or a color wheel graph is a technique for visualizing complex functions by assigning a color to each point of the complex plane. By assigning points on the complex plane to different colors and brightness, domain coloring allows for a function from the complex plane to itself — whose graph would normally require four space dimensions — to be easily represented and understood. This provides insight to the fluidity of complex functions and shows natural geometric extensions of real functions. (Wikipedia).

Domain Coloring the Real Number Line // #SoME2 [ALGEBRA] [ANALYSIS]

I wanted to do something special for Grant Sanderson's (of  @3Blue1Brown  fame) Summer of Math Exposition 2, so I decided to work out an idea I've had for a while: what if we visualized a real-valued function along the number line using a domain coloring, similarly to how we can visualize

Determining the domain and range from a table of values - Free Math Help

http://www.freemathvideos.com In this video series I show you how to find the domain and range from a table, graph, or relation as a set of mapping. The domain is the set of all input values where the range is the set of all output variables.

Edge Colorings and Chromatic Index of Graphs | Graph Theory

We introduce edge colorings of graphs and the edge chromatic number of graphs, also called the chromatic index. We'll talk about k-colorings/k-edge colorings, minimum edge colorings, edge colourings as matchings, edge colourings as functions, and see examples and non-examples of edge color

Learn how to determine the domain and range of a function given the graph of the function. Since the domain of a function is the set of all x-values we will want to identify how far left the graph goes as well as how far right to determine the domain. For the range we want to determine h
