Planes, Solutions, and Gaussian Elimination of a 3*3 Linear System

http://demonstrations.wolfram.com/Pla... The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. Gaussian elimination is often used as a pen-and-paper exercise for solving simple linear systems, but the geometric counterpart may remain elusive during this exercise. Use this Demonstration to visualize the planes and solutions of a system of three li... Contributed by: Klaus Michelsen
