We use linear algebra In many applications ,electrical circuit ,genetic and cryptography. Linear algebra is a branch of mathematics that studies systems of linear equations and the properties of matrices. Marginal Cost MC 1. 6) Weighted Least-Squares-Application of inner product space. In other words, a linear equation is an equation that is written for two different variables. Money problems by using two variables It is commonly linked with vector spaces but is more simply a means to solving systems of linear equations. If C(x) is linear, then MC is the slope of the cost function. Leontief Economic models Matrix theory has been very successful in describing interrelations among prices, outputs, and demands in economic systems. Linear algebra is a fundamental area of mathematics, and is arguably the most powerful mathematical tool ever developed. 4 - 5.2 (Klein).
