                                                11 Samacheer Maths Solutions for 7.2.21

                                                One of the oldest concepts in mathematics is metaphysics and Determinants.ItTrademarkia has hasThe concepts were well developed during the 17th Century.When the mathematicians tried to solve the problem with multiple simultaneous linear equations matrices and determinants were needed.Some of the clay tablets created with the matrices that are still preserved were created during the Babylonians era.

                                                This can apply to the normal life.The matrices are used in analytic applications to solve complex problems using a computer.Predicting and model developments using matrices are included in analytic problems.The word matrix was invented by a lawyer and a mathematician in 17th century.The concept of matrix was an important part of mathematics.

                                                In terms of arranging cars in a parking area coconut trees in a farm land and storage of boxes in a storage area we can see the same matrices.The basis for the term will be found in the form of the quadratic form.This was invented in 17th century by Gauss.The concept of determinants was expanded by another person.The coefficients of the linear equation can be written with the help of matrices.

                                                In data is represented in excel spread sheet as matrices and is used in almost all corporates and educational institutionsMany of the dashboards developed for management decision making and operational analysis are also in a matrices format with tables that comprise of rows and columnsA table with years in the columns and states in the rows can be used to show the population in India over the last 10 years.The elements are distributed in rows and columns in the matrix.We usually put a square brackets over the rows and columns to tell us what the matrix is.

                                                The size of the matrices is determined by the multiplication of A * B if the matrices have A number of rows and B number of columns.If the matrices have 10 rows and 5 columns the size of the matrices is 50.The matrix that only has a single row is called a row matrices.column matrices are matrices that only have one column.The zero matrices are a type of matrices that have zero elements.

                                                It is also called a null Matrix.The squares have the same amount of row elements and column elements.The principal diagonal of the square matrix is represented by elements that fall in the diagonal line.Different names are given to the principal diagonal.It is called diagonal main diagonal or leading diagonal elements.

                                                The unit matrix only has values in the diagonal and the rest of the elements are all zero.The elements will have a value of 1 if they are diagonal.triangular matrix is a type of matrix that is square.If all the elements in the bottom of the diagonal are zero then it's a triangular matrix.If all the elements of the matrices are equal we can say that both matrices are equal.

                                                If any of the elements are not the same or in the same order then it is called an equal matrix.In addition multiplication and subtraction are some operations we can do.The division of two matrices is difficult.Before we perform the operations there are certain conditions to be satisfied.If we have to multiple a matrix with a constant then we need to add up all the elements of the matrices with the same element.

                                                If the matrices have the same number of rows and columns we can do addition and subtraction of them.The addition of matrix A with matrix B indicates the A+B of each of the elements of the matrices.The elements of the matrices are indicated by the addition of Matrix A with matrix B.If the number of rows and columns in one matrix is the same as the number of rows and columns in the other matrix we need to add or subtract matrices.We need to mention in the result that it is not possible to add or subtract something.
