Answer to Problem 21E
The inverse of given matrix doesn’t exist.
Explanation of Solution
Given:
Concept used:
Steps to solve the inverse of matrix by
Step1: calculating the matrix of minors.
Step2:turn that into the matrix of cofactors.
Step3: then ad jugate by transposing the cofactor.
Step4: last multiply by the
Formula for inverse of matrix A is:
Calculation:
Here
Cofactor of A:
Cofactor of A:
Ad jugate of A:
The inverse of A is
Since the denominator is 0 so, it’s impossible to solved the matrix further
Hence, the inverse of given matrix doesn’t exist.
