There are two matrices which are very important and are used in many applications. They are the identity and inverse matrices. In this tutorial I explain what their properties are and how to calculate them for 2×2 matrices.
Example on singular matrices
Example on solving a matrix equation
Here is an example on how we can use the identity and inverse properties of a matrix to solve matrix equations.
Example on proving a matrix identity
Here is an example on how we can use the identity and inverse properties of a matrix to prove a matrix identity.
