Usually a matrix contains numbers or algebraic expressions.
Matrices and Determinants:. In Mathematics, one of the interesting, easiest and important topic is Matrices and Determinants. Every year you will get at least 1 - 3 questions in JEE Main and other exams, directly and indirectly, the concept of this chapter will be involved in many other chapters, like integral and differential calculus. Concept of this chapter will be used for the axis-transformation concept.
As we have seen in past lessons, in order to define what is a determinant of a matrix we need to go back a to our definition of a matrix. Remember that we have learnt that a matrix is an ordered list of numbers put in a rectangular bracket. This list can also be called a rectangular array, and it provides an orderly fashion to display a "list" of information elements. If you want to review the definition of the matrix with more detail you can revisit our lesson on notation of matrices. A matrix describes a linear transformation or linear map, which is a kind of transcription between two types of algebraic structures, such as vector fields. In that way, we can resolve systems of linear equations by representing a linear system as a matrix. The matrix representation of a linear system is made by using all of the variable coefficients found in the system, and use them as element entries to construct the rectangular array of an appropriate size augmented matrix.
It has 2 rows and 4 columns. We usually write matrices inside parentheses or brackets [ ]. We use matrices to solve simultaneous equations , that we met earlier. Matrices are used to solve problems in:. We see several of these applications throughout this chapter, especially in Matrices and Linear Equations.
Being one of the fundamentals of algebra, it is essential for every aspirant to have clear concepts and sufficient practice. The elements in a square matrix for which the number of the row is equal to the number of the column is called the leading diagonal or the principle diagonal of the matrix. A square matrix is called idempotent if the product of the matrix with itself results in the same matrix. A matrix in which the element of the i th row and j th column is equal to the element of the j th row and i th column. A matrix in which the element of the i th row and j th column is equal to the negative of the element of the j th row and i th column, such that all elements of the principle diagonal are zero.

Вот. Он печально на нее посмотрел. - Мидж… у меня нет никакой жизни. Она постучала пальцем по кипе документов: - Вот твоя жизнь, Чед Бринкерхофф. - Но, посмотрев на него, смягчилась. - Могу я чем-нибудь тебе помочь, прежде чем уйду. Он посмотрел на нее умоляюще и покрутил затекшей шеей.
ТРАНСТЕКСТ. Правда о ТРАНСТЕКСТЕ. Сьюзан понимающе кивнула. Это звучало вполне логично: Танкадо хотел заставить АНБ рассказать о ТРАНСТЕКСТЕ всему миру. По сути, это был самый настоящий шантаж. Он предоставил АНБ выбор: либо рассказать миру о ТРАНСТЕКСТЕ, либо лишиться главного банка данных.
Сьюзан, чуть подтолкнув, усадила его на место. - Нет! - рявкнула. - Пойду я! - Ее тон говорил о том, что возражений она не потерпит. Стратмор закрыл лицо руками. - Хорошо.
