Eigenvectors in 2D

Select the coefficients of the matrix A and drag the red arrow. The blue arrow shows the result of multiplication by A. An eigenvector is represented by the alignment of the two arrows; the eigenvalue is the ratio of their lengths. The arrows can align twice, once, or not at all, depending on whether A has two eigenvalues, a single one, or no real eigenvaluesComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemátic
