## Class 12 Matrices Chapter Wise Handwritten Notes PDF

Matrices are a useful tool in mathematics and have numerous applications in various fields such as physics, engineering, and computer science. A matrix is a collection of numbers arranged in a rectangular grid. The size of a matrix is described by its dimensions, which are the number of rows and columns it has. For example, a matrix with 3 rows and 4 columns is called a 3×4 matrix. Matrices are usually denoted by capital letters, such as A, B, C, etc. The elements of a matrix are usually denoted by lowercase letters with subscripts, such as aij, where i and j represent the row and column indices, respectively.

There are several operations that can be performed on matrices, such as addition, subtraction, multiplication, and inversion. Matrix addition is performed by adding the corresponding elements of two matrices. For example, if A and B are two matrices of the same size, their sum is denoted by A + B and is obtained by adding the corresponding elements of A and B. Matrix subtraction is performed by subtracting the corresponding elements of two matrices. For example, if A and B are two matrices of the same size, their difference is denoted by A – B and is obtained by subtracting the corresponding elements of B from those of A.

Matrix multiplication is a more complex operation that involves multiplying rows of one matrix by columns of another matrix and summing the products. The result is a new matrix with dimensions determined by the size of the matrices being multiplied. For example, if A is a 3×2 matrix and B is a 2×4 matrix, their product, denoted by A * B, is a 3×4 matrix. It is important to note that matrix multiplication is not commutative, meaning that A * B is not necessarily equal to B * A.

The inverse of a matrix, denoted by A^(-1), is a matrix that, when multiplied by the original matrix, yields the identity matrix (a matrix with 1s on the diagonal and 0s everywhere else). Not all matrices have inverses, so it is important to check whether a matrix is invertible before attempting to find its inverse. Inverting a matrix can be a useful tool for solving systems of linear equations, which are often represented using matrices.

There are several applications of matrices in various fields. In physics and engineering, matrices can be used to represent linear transformations such as rotations and scalings. In machine learning, matrices are often used to represent data in the form of features and labels.

There are several special types of matrices that have specific properties and applications. A square matrix is a matrix with the same number of rows and columns, such as a 2×2 or 3×3 matrix. A diagonal matrix is a square matrix with 0s everywhere except for the elements on the diagonal (from the top left to the bottom right). The identity matrix is a special type of diagonal matrix with 1s on the diagonal and 0s everywhere else. The identity matrix is often denoted by I and is used as a neutral element in matrix operations, such as A * I = A.

Symmetric matrices are square matrices that are equal to their transpose (the matrix obtained by flipping the matrix along its diagonal). Skew-symmetric matrices are square matrices that are equal to the negative of their transpose. Orthogonal matrices are square matrices with the property that their inverse is equal to their transpose. Unitary matrices are square matrices with the property that their inverse is equal to their conjugate transpose.

In conclusion, matrices are a powerful tool in mathematics with numerous applications in various fields. They can be used to represent and manipulate data, solve systems of linear equations, and represent linear transformations. There are also several special types of matrices with specific properties and applications.

## Class 12th Matrices Handwritten Notes Preparation Tips

Here are some tips for preparing handwritten notes for Class 12th Matrices:

• Start by reviewing the syllabus and identifying the key concepts that you need to cover.
• Look for multiple sources of information, including textbooks, online resources, and lectures.
• Use diagrams and examples to help illustrate complex concepts.
• Practice regularly by solving problems and reviewing your notes.
• Seek help if you are struggling to understand a concept or solve a problem.

## Applications of Matrices in Mathematics

1 . What is the product of the following matrices?

A = [1 2; 3 4]

B = [5 6; 7 8]

The product of A and B is:

A * B = [19 22; 43 50]

2 . What is the inverse of the following matrix?

C = [2 1; 1 2]

The inverse of C is:

C^(-1) = [1 -1; -1 2]

3 . What is the determinant of the following matrix?

D = [1 2 3; 4 5 6; 7 8 9]

The determinant of D is:

det(D) = 0

4 . What is the transpose of the following matrix?

E = [1 2 3; 4 5 6]

The transpose of E is:

E^T = [1 4; 2 5; 3 6]

I hope these examples help illustrate some of the operations and concepts involving matrices. Let me know if you have any further questions!
