- 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:
- Determinant | Meaning, Properties, Definition | Britannica
Determinant, in linear and multilinear algebra, a value, denoted det A, associated with a square matrix A of n rows and n columns

A Determinant is a scalar value computed from a square matrix that tells us whether the matrix is invertible, how it scales space, and whether a system of equations has a unique solution For a matrix A, the determinant is written as det (A) or |A|
- The Determinant: How It Works and What It Tells Us - DataCamp
A determinant is a fundamental property of a square matrix that plays significant direct and indirect roles in matrix operations, such as invertibility, solving linear systems in engineering, and transformations in geometry and computer graphics
- Determinant of Matrix - 2x2, 3x3, 4x4, Finding Determinant
The determinant of matrix is the sum of products of the elements of any row or column and their corresponding cofactors Learn the step by step process of finding determinant of matrix along with some useful shortcuts
- 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)
- Lecture 18: Properties of determinants - MIT OpenCourseWare
The determinant is a number associated with any square matrix; we’ll write it as det A or |A| The determinant encodes a lot of information about the matrix; the matrix is invertible exactly when the determinant is non-zero
