The Formula Explained

The eigenvalues of a matrix \( A \) are obtained by solving the characteristic equation \( \det(A - \lambda I) = 0 \).

Glossary of Terms

How It Works: A Step-by-Step Example

For a 2x2 matrix \(\begin{bmatrix} 4 & 1 \\ 2 & 3 \end{bmatrix}\), the eigenvalues can be calculated as \(\lambda = 3, 4\) and the corresponding eigenvectors can be \(\begin{bmatrix} 1 \\ 1 \end{bmatrix}\) and \(\begin{bmatrix} 1 \\ -2 \end{bmatrix}\).
