Question

Define minors and cofactors in mathematics

Answer 1

Holaaaa Mate

Answer:

Minors and cofactors are two of the most important concepts in matrices as they are crucial in finding the adjoint and the inverse of a matrix. To find the determinants of a large square matrix (like 4×4), it is important to find the minors of that matrix and then the cofactors of that matrix. Below is a detailed explanation on “what are minors and cofactors” along with steps to find them.

Answer 2

• Cofactor is the number you attain on removing the column and row of a particular element existing in a matrix. Cofactor is a sign(+ or -) minor of that element.

• Minor is the square matrix's determinant whose formation takes place by deleting one column and one row from some larger square matrix. Minor of a matrix is a determinant which is obtained by deleting the row and column in which the element occur
