What Is the Determinant of a Matrix?
The **determinant** is a unique scalar value associated with a square matrix. It serves as a fundamental indicator in linear algebra, informing whether the matrix is invertible and if an associated system of linear equations has a unique solution. Its calculation is essential for solving linear systems, inverting matrices, and various applications in geometry, physics, and engineering.
