The eigenvalues of a matrix are the scalars by which eigenvectors change when some transformation is applied to them. Learn how to find the eigenvalues of 2x2 and 3x3 matrices using the characteristic equation with examples.
We know that for a given n×n matrix A, the characteristic equation |A−λI|=0 has n solutions, counted with multiplicity. So for a given 2x2 matrix A, the characteristic equation will be a quadratic polynomial of the form aλ2+bλ+c=0 with roots λ=−b±b2−4ac2a by the ...
For any nxn square matrix, there is n number of eigenvalues. A 2x2 matrix has 2 eigenvalues and a 3x3 square matrix has 3 eigenvalues. However, finding the eigenvalues for a 2x2 matrix requires solving the quadratic eigenvalues equation, which can have two solutions, one repeated solution, ...
