Understanding Matrix Determinants
The determinant is a special number that can be calculated from a square matrix. It is denoted by det(A) or |A|. Determinants are widely used in linear algebra for solving systems of linear equations, among other applications.
How to Calculate a Determinant
To compute it for a 2x2 matrix:
\[ \begin{bmatrix} a & b \\ c & d \\ \end{bmatrix} \]
The determinant is calculated as: ad - bc.
For larger matrices, determinants are computed using more complex methods such as the Laplace expansion.
