Wonders of Mathematics: Matrices


Matrix theory is a beautiful and useful area of mathematics. It is used in the solution of most engineering problems: for example, when calculating the forces a bridge has to withstand, in the lighting of a video game, in removing excessive things from photograph and in Google search. Students of mathematics begin studying matrix theory during their first year in university. In this video I give a simple example of how matrices can be used to solve a problem about spiders and lizards. We also see how the same problem can be solved with an equation pair familiar from high school.
