How to find the eigenvalues and eigenvectors of a 2x2 matrixSet up the characteristic equation, using |A − λI| = 0 Solve the characteristic equation, giving us the eigenvalues (2 eigenvalues for a 2x2 system) Substitute the eigenvalues into the two equations given by A − λI Choose...
Example: Find Eigenvalues and Eigenvectors of the 2x2 Matrix All that's left is to find two eigenvectors. Let's find the eigenvector, v1, connected with the eigenvalue, λ1=-1, first. In this case, we find that the first eigenvector is any 2 component column vector in which the two...

The study of eigenvalues and eigenvectors is the first step into an area of mathematics called spectral theory. How many eigenvalues does a 2x2 matrix have? A 2 x 2 matrix will always have two eigenvalues, counted with multiplicity. Since we compute these eigenvalues using the characteristic ...
This calculator allows you to enter any square matrix from 2x2, 3x3, 4x4 all the way up to 9x9 size. It will find the eigenvalues of that matrix, and also outputs the corresponding eigenvectors.For background on these concepts, see 7. Eigenvalues and Eigenvectors ...
