Topics in Determinants
1
Introduction to Determinants
- A determinant is a scalar value calculated from a square matrix
- Determinants exist only for square matrices (n×n)
- Denoted by |A| or det(A) for matrix A
2
Expansion of Determinants and Minors & Cofactors
- Minor Mij: determinant after removing ith row and jth column
- Cofactor Cij = (-1)^(i+j) × Mij
- Determinant expansion: Δ = Σ(aij × Cij) for any row or column
3
Properties of Determinants
- Property 1: |A| = |A^T| (transpose doesn't change value)
- Property 2: Interchanging rows/columns changes sign
- Property 3: Identical rows/columns make determinant zero
4
Standard Determinant Forms
- Vandermonde determinant: |1 1 1 | = (x-y)(y-z)(z-x)
- |x y z |
- |x² y² z²|
