- Determinant of a Matrix - Math is Fun
To work out the determinant of a 3×3 matrix: Multiply a by the determinant of the 2×2 matrix that is not in a 's row or column As a formula (remember the vertical bars || mean "determinant of"): "The determinant of A equals a times the determinant of etc" The pattern continues for 4×4 matrices: As a formula:

Determinants are the scalar quantities obtained by the sum of products of the elements of a square matrix and their cofactors according to a prescribed rule They help to find the adjoint, inverse of a matrix

- Determinant -- from Wolfram MathWorld
Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations As shown by Cramer's rule, a nonhomogeneous system of linear equations has a unique solution iff the determinant of the system's matrix is nonzero (i e , the matrix is nonsingular)
