Determinant of a inverse

WebThe 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 calculate the determinant of the given matrix. If the determinant is not equal to 0, then it is an invertible matrix otherwise not. WebIf the determinant is non-zero the matrix has a unique inversion, which means that if the matrix represents a system of linear equations, then the system also has a unique solution. So calculating the determinant can save you a lot of work trying to find a solution to a system of equations that has no solution.
