# How to determine if a 3x3 matrix has an inverse

This implies that only classical inverse of A satisfies the equation A (A^-1)=I_n. And the rank of the matrix is not full if it has - zero column or row, - column (row) that is equal to

## Inverse of a Matrix using Minors, Cofactors and Adjugate

The steps required to find the inverse of a 3×3 matrix are: Compute the determinant of the given matrix and check whether the matrix invertible Calculate the determinant of 2×2 minor matrices Formulate the matrix of cofactors Take

## Inverse of a 3 by 3 matrix

The steps to find the inverse of the 3 by 3 matrix are given below. Step 1: The first step while finding the inverse matrix is to check whether the given matrix is invertible. For this, we need to

## Inverse of 3x3 Matrix

The first step is to calculate the determinant of the 3 * 3 matrix and then find its cofactors, minors, and adjoint and then include the results in the below-given inverse matrix formula. A −
