We are given with two invertible matrices A and B, how to prove that
?
We know that if A.B
then it means B is inverse of matrix A where
is an identity matrix.
If, we can prove that
.
then it means that
is inverse of
.
In other words proving
.
Lets simplify
.
{
and
}
Therefore, from above equation, we can say that
is inverse of
which is the desired equation.
