Question

write the formula of determinant and matrix? ​

Answer 1

To every square matrix A = [aij] of order n, we can associate a number (real or complex) called determinant of the square matrix A, where a = (i, j)th element of A. This may be thought of as a function which associates each square matrix with a unique number (real or complex).

This may be thought of as a function which associates each square matrix with a unique number (real or complex).If M is the set of square matrices, K is the set of numbers (real or complex) and f : M → K is defined by f (A) = k, where A ∈ M and k ∈ K, then f (A) is called the determinant of A. It is also denoted by | A | or det A or Δ.

• ➪ write the formula of determinant and matrix ???

$★ \: \: SOLUTION \: \: ★$

• ➪ The determinant is: |A| = a (ei − fh) − b (di − fg) + c (dh − eg). The determinant of A equals 'a times e x i minus f x h minus b times d x i minus f x g plus c times d x h minus e x g'. ... Multiply 'a' by the determinant of the 2×2 matrix that is not in a's row or column. Likewise for 'b' and for 'c'
