🔷08 - Inverse of 2x2 and 3x3 Matrices - Minors, Cofactors and Adjoint of a Matrix
In this video we are going to learn how to find the inverse of a 2x2 and a 3x3 matrix.
For 3x3 matrix, we shall find the minors, cofactor and adjoint of the 3x3 matrix.
A matrix is a rectangular array of numbers that are arranged into rows and columns.
Order of matrix is written in the form - (row x column)
The values that make up the matrix are called elements or entries
Types of Matrices
1. Row matrix
2. Column matrix
3. Equal Matrices matrix
4. Addition and Subtraction of Matrices
5. Properties of Matrix Addition
6. Scalar Multiplication of Matrices
7. Multiplication of Matrices
8. Properties of Matrix Multiplication
