Question

inverse of identity matrix is​

Answer 1

Explanation:

Is the same identity matrix.........

Answer 2

Explanation:

An inverse A of a matrix M is one such that AM=MA=I .

For the identity matrix M=I , this means AI=IA=I . Note that the identity is the unique matrix I such that IM=MI=I , so letting M here take the place of I , the only matrix inverse A satisfying this relation is also I .
