Set the matrix must be square and append the identity matrix of the same dimension to it. To find the inverse of a 3 by 3 matrix is a little critical job but can be evaluated by following few steps. Inverting a 3x3 matrix using determinants part 2. I m now going to do one of my least favorite things to do by hand and that is to invert a 3 by 3 matrix.

A singular matrix is the one in which the determinant is not equal to zero. Inverse of a 3 by 3 matrix as you know every 2 by 2 matrix a that isn t singular that is whose determinant isn t zero has an inverse a 1 with the property that a a 1 a 1 a i 2 where i 2 is the 2 by 2 identity matrix left begin array cc 1 0 0 1 end array right. If a determinant of the main matrix is zero inverse doesn t exist. As a result you will get the inverse calculated on the right.
