Application of Matrices to Real Life Problems CHAPTER ONE INTRODUCTION AND LITERATURE REVIEW INTRODUCTION. Applications of Linear Equations. If the linear equation has two variables, then it is called linear equations in two variables and so on. One could argue that the main technique in applied math is to transform a given hard problem into linear algebra so that it can be solved easily. Example: A cereal company finds that if it spends $40,000 on advertising, then 100,000 boxes of cereal will be sold, and of it spends $60,000, then 200,000 boxes will be sold. Let us look at an example to understand this better. Linear Graph Equation. In short, matrices are a compact representation of linear transformations applied to a vector space, so that all points in that space are stretched and skewed from their . ; Step 2: Identify the variables by assigning a letter or expression to the unknown quantities. A linear equation is an equation of degree one.. As this question was posted in the Linear Algebra and Group Theory section it seems reasonable to assume it was referring to the theorem that the order of any group is an integer multiple of that of any of it's subgroups (proof is easy - try it; hint - use the definition of cosets) Whether it applies in so-called daily life, I have no idea. In physics the relation of groups with symmetries means that group theory plays a huge role in the formulation of physics. Other real-world applications of linear algebra include ranking in search engines, decision tree induction, testing software code in software engineering, graphics, facial recognition, prediction and so on.
