matrix is zero, then it will not have an inverse, and the matrix is said to be singular Only non-singular matrices have inverses 2 A formula for finding the inverse

In this leaflet we consider how to find the inverse of a 3×3 matrix Before Here is the matrix A that we saw in the leaflet on finding cofactors and determinants
