              11 Samacheer Maths Solutions for 7.4.1

              One of the oldest concepts in the field of mathematics is the conjugates and Determinants.It hasTrademarkia has hasTrademarkiaTheconcepts were developed in the 17th century.When the mathematicians tried to solve the problem of multiple simultaneous linear equations they needed matrices and determinants.Some of the clay tablets created with the matrices which are still preserved are from the Babylonians.

              This works in the normal life.In modern application the matrices are used to solve complex problems using the computer.The model developments using matrices are included in the analytic problems.A mathematician and a lawyer created the word matrix in the 17th century.There is a powerful application to the concept of matrix.

              In terms of organised cars in a parking area coconut trees in a farm land and the storage of boxes in a storage area we can see matrices.The basis of the term is found in the form of the quadrangular form.Gauss was the creator of this in the 17th century.The notion of determinants was expanded by another mathematician.The coefficients of the linear equation are written with matrices.

              In data is represented in excel spread sheet as a matrices and is used in almost all corporates and educational institutionsA lot of the dashboards developed for management decision making and operational analysis are in a matrices format with tables with rows and columns.A table with years in the columns and states in the rows can be used to depict the population of India over the past decade.A rectangular array of elements are distributed in two dimentionals.The rows and columns are usually covered with a square brackets to indicate that there is a matrix within it.

              If the matrices have a number of rows and columns then the size of the matrices is determined by the number of rows and columns.If a matrix has 10 rows and 5 columns the size of the matrices is 50.The row matrices are the matrices that only have one row.The matrices that only have one column are known as column matrices.The zero matrices are a type of matrices with all elements being 0.

              It's called a null matrix or void matrix.The squares have equal number of row elements and column elements.There are elements in the diagonal line that represent the principal diagonal in a square matrix.The main diagonal has different names.Diagonal main diagonal or leading diagonal elements are what they are called.

              The unit matrix only has values in the diagonal and the rest is all zero.In the diagonal elements all elements have the same value.A triangular matrix can be found on the square matrix.If the bottom of the diagonal is zero then the triangular matrix is called square matrix.If all the elements of the matrices are equal then we can say that the two matrices are equal.

              If any of the elements is not the same or not in the same order then it is called an equal matrix.Adding subtracting and multiplication are some of the operations we can do on matrices.There isn't a way to division two matrices.There are certain conditions that need to be satisfied before we can do the operations.If we have to multiple a matrix with a constant then we need to multiply all the elements of the matrices with a single element.

              If the matrices have the same number of rows and columns we can add or subtract matrices.Adding matrix A with matrix B will show A+B of the elements of the matrices.The A-B of the elements of the matrices are shown 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 then we need to add or subtract matrices.We need to mention in the result that adding or subtracting something isn't possible if not.
