VERIFY THAT THE MATRICES ARE INVERSES OF EACH OTHER

Verify that the matrices are inverses of each other.

Example 1 :

Solution :

So, AB  =  BA  =  I₂ (Identity matrix)

Hence verified.

Example 2 :

Solution :

So, AB  =  BA  =  I₂ (Identity matrix)

Hence verified.

Example 3 :

Solution :

So, AB  =  BA  =  I₃ (Identity matrix)

Hence verified.
