Topics in Determinants
Introduction to Determinants
- Determinant is a numerical value associated with every square matrix
- Denoted by |A|, det(A), or Δ (delta)
- Only defined for square matrices (n×n)
Properties of Determinants
- If two rows (or columns) are identical, determinant = 0
- Interchanging two rows (or columns) changes sign of determinant
- If one row (or column) is multiple of another, determinant = 0
Area of Triangle Using Determinants
- Area formula uses coordinates of three vertices
- Always take absolute value for area (positive quantity)
- If area = 0, points are collinear
Minors and Cofactors
- Minor Mᵢⱼ = determinant after removing ith row and jth column
- Cofactor Cᵢⱼ = (-1)^(i+j) × Mᵢⱼ
- Sign pattern alternates in checkerboard fashion
