Among all the chapters that you will study for your IIT-JEE mains maths video, matrix is one of the simple and scoring topics of all. Students will find it very simple to understand and to solve the problems as well. Matrix is one of the most interesting chapters in your IIT-JEE maths examination syllabus as well. It is simple, bit of learning and calculations. Though you do not get many question in IIT-JEE examinations.
Matrix is mostly the work of arrangement. The notation for matrix is denoted by two [ ] this. And you have certain elements in it. This arrangement has a certain meaning. And because of this meaning, the arrangement of matrix is made under the bracket. This is done so that sensible information can be derived from the arrangement.
In mathematics, matrices are of great importance as it helps to solve the equations easily. Also this is one of the important chapters of your 12th standard curriculum. Especially if you look at electrical engineering field, students will get lot of problems based on matrices.
In this video lecture on IIT-JEE mathematics examination, we will learn about matrix and its implementation with simple examples. Matrix algebra is vast but is very interesting topic. Elements in matrix can be a11 a12 a13 a14 etc.
The element of a matrix say aij will be member of ith row and jth column. As simple the chapter is, so it is simple to make silly mistakes. Remember to solve the sums properly so as to get correct results. The elements horizontally placed in a matrix are rows and those placed vertically are columns.
As shown in an example, 2, 6, 1 are the example of elements in a row and 2, 6, 7 are the examples of the elements in the column. Respectively you will find number and number of columns in each matrix.
In matrices one of the most important things is to maintain the order. This means that order of matrices should be same to compute the rest of the problem. In these IIT-JEE maths video, you will be able to find illustrative examples based on the order of the matrix as well.
Apart from this there are various types of matrix which you will be learning in these JEE video lectures such as square matrix, diagonal matrix etc.
