Matrices Class 12 Solutions PDF Free Download

In Class 12, matrices are an important topic in mathematics. Matrices are rectangular arrays of numbers or symbols that are arranged in rows and columns. They have various applications in different fields, such as physics, computer science, economics, and more. To understand matrices in Class 12, you need to grasp the basic concepts and operations associated with them.

Matrices can be classified based on their size. A matrix with m rows and n columns is called an m x n matrix. Matrices can also be categorized as square matrices, where the number of rows is equal to the number of columns. Additionally, matrices can be classified as row matrices, column matrices, or diagonal matrices based on their arrangement.

Step-by-step solutions for common Class 12 matrices problems

To help you excel in Class 12 matrices, here are step-by-step solutions for some common problems:

Problem 1: Addition of Matrices

Given two matrices A and B, find the sum of the matrices.

Solution:

1. Identify the order or size of the matrices A and B.
2. Ensure that the sizes of the matrices are compatible for addition (i.e., they have the same number of rows and columns).
3. Add the corresponding elements of the matrices to obtain the sum.
4. Write the sum matrix in the same order as the original matrices.

Example: Copy code

A = [1 2 3] [4 5 6] B = [7 8 9] [10 11 12] A + B = [1+7 2+8 3+9] [4+10 5+11 6+12]

Problem 2: Multiplication of Matrices

Given two matrices A and B, find the product of the matrices.

Solution:

1. Identify the order or size of the matrices A and B.
2. Ensure that the sizes of the matrices are compatible for multiplication (i.e., the number of columns in matrix A is equal to the number of rows in matrix B).
3. Multiply the corresponding elements and sum them up to obtain the elements of the product matrix.
4. Write the product matrix in the order specified by the sizes of matrices A and B.

Example: Copy code

A = [1 2] [3 4] B = [5 6] [7 8] A * B = [1*5+2*7 1*6+2*8] [3*5+4*7 3*6+4*8]

Problem 3: Determinant of a Matrix

Given a matrix A, find its determinant.

Solution:

1. Identify the order or size of the matrix A.
2. Ensure that the matrix is square (i.e., the number of rows is equal to the number of columns).
3. Apply the determinant formula based on the size of the matrix (e.g., 2×2, 3×3, etc.).
4. Evaluate the determinant using the formula and calculate the final result.

Example: Copy code

A = [3 2] [1 4] Determinant of A = (3*4) - (2*1) = 10

By following these step-by-step solutions, you can gain a better understanding of solving common Class 12 matrices problems and improve your proficiency in the subject.
