Addendum: Inverting a 2x2 matrix To invert a 2x2 matrix, you first find the determinant. Consider the matrix: 11 34 = A The determinant of A is given by: () det 1*41*3431 = −=−= A The next step is to do the **cofactor** matrix.

Learning Outcomes At the end of this section you will be able to: † Understand what a **cofactor** is, † Calculate the determinant ofa (3 £ 3) matrix using the **cofactor** approach, † Calculate the inverse ofa (3 £ 3) matrix using the **cofactor** approach.
