Assertion about Square Matrix
Sum of Eigen Values
The sum of eigenvalues of a square matrix is equal to the trace of the matrix.
Product of Eigen Values
The product of eigenvalues of a square matrix is equal to the determinant of the matrix.
Non-zero Eigen Values
All eigenvalues of a square matrix are non-zero, if and only if the matrix is non-singular.
Eigen Values of Inverse Matrix
If A-1 exists, then the eigenvalues of A-1 are equal to the reciprocal of the eigenvalues of A.
Correct Assertion
All the above assertions are correct.
Explanation
- The sum of eigenvalues of a matrix is equal to the trace of a matrix. This is because the trace of a matrix is equal to the sum of its diagonal elements, which are also the eigenvalues of the matrix.
- The product of eigenvalues of a matrix is equal to the determinant of a matrix. This is because the determinant of a matrix is equal to the product of its eigenvalues.
- All eigenvalues of a matrix are non-zero if and only if the matrix is non-singular. This is because a matrix is singular if and only if its determinant is zero, which means at least one of its eigenvalues is zero.
- If A-1 exists, then the eigenvalues of A-1 are equal to the reciprocal of the eigenvalues of A. This is because the eigenvalues of A-1 are the inverse of the eigenvalues of A.
Hence, all the given assertions are correct and option D is the correct answer.
