This document contains denitions of some of the important terms used in linear algebra.
In mathematics linear refers to an equation or function that is the equation of a straight line and takes the form y mx b where m is equal to the slope and b is equal to the y intercept.
A linear equation is an algebraic equation such as y 4x 3 in which the variables are of the first degree that is raised only to the first power.
The motivation for insisting on this is that when we want to do linear algebra we need things to be linear spaces.

Illustrated definition of linear equation. A system of linear equations a x b is homogeneous if b 0. Two systems of linear equations in n unknowns are equivalent if they have the same set of solutions. Denitions of linear algebra terms in order to learn and understand mathematics it is necessary to understand the meanings of the terms vocabulary words that are used. A linear function is any function that graphs to a straight line.

What this means mathematically is that the function has either one or two variables with no exponents or powers. Linear algebra is the branch of mathematics concerning linear equations such as. The graph of such an equation is a straight line. Linear algebra definition is a branch of mathematics that is concerned with mathematical structures closed under the operations of addition and scalar multiplication and that includes the theory of systems of linear equations matrices determinants vector spaces and linear transformations.

An arbitrary subset of a linear space like say a cantor set has nothing to do with linear algebra methods so the definition is made to exclude such things. Lets get our feet wet by thinking in terms of vectors and spaces. Home math algebra what does linear mean in mathematics.
