Question

Find the minors of the matrix A 1*3

Answer 1

A 1x3 matrix only has one entry, so there is only one minor, which is the determinant of the matrix itself.

For example, if A = [a, b, c], then the minor of A is simply:

|A| = det(A) = a

Since the determinant of a 1x1 matrix is just its single entry.
