... where 0n is the n-by-n zero matrix. The main use of this is that the eigenvalues of T are the roots of PT (x) = 0. However, except for very small matrices, this is a suboptimal computational approach, and the minimal polynomial is far more useful for demonstrating qualitative facts about endomorphis ...

Linear Combinations and Ax + By = C
... The form y = mx + b is convenient for graphing lines because the y-intercept and slope are obvious, but you have also seen many equations for lines in different forms. For example, in the rectangle with length , width w, and perimeter 20 inches, 20 = 2 + 2w. This is a linear equation, and the expr ...

... Now that we have seen all the possibilities, we can answer the above questions: 1.) Do they intersect? Not always. In this case, we say there is no solution. 2.) If they do intersect, what is the point of intersection? When we can find a single point of intersection, we write out the ordered pair as ...

Linear algebra
Linear algebra is the branch of mathematics concerning vector spaces and linear mappings between such spaces. It includes the study of lines, planes, and subspaces, but is also concerned with properties common to all vector spaces.The set of points with coordinates that satisfy a linear equation forms a hyperplane in an n-dimensional space. The conditions under which a set of n hyperplanes intersect in a single point is an important focus of study in linear algebra. Such an investigation is initially motivated by a system of linear equations containing several unknowns. Such equations are naturally represented using the formalism of matrices and vectors.Linear algebra is central to both pure and applied mathematics. For instance, abstract algebra arises by relaxing the axioms of a vector space, leading to a number of generalizations. Functional analysis studies the infinite-dimensional version of the theory of vector spaces. Combined with calculus, linear algebra facilitates the solution of linear systems of differential equations.Techniques from linear algebra are also used in analytic geometry, engineering, physics, natural sciences, computer science, computer animation, and the social sciences (particularly in economics). Because linear algebra is such a well-developed theory, nonlinear mathematical models are sometimes approximated by linear models.
