[b]Eigenvalue-Eigenvector Visualization[/b]:[br]Move the vector [math]v[/math] and change the matrix [math]\begin{pmatrix} a & b \\ c & d \end{pmatrix}[/math] to visualize the eigenvector-eigenvalue pairs. To approximate the eigenvalues, move [math]v[/math] so that it is parallel to [math]Av[/math]. The vector [math]v[/math] is restricted to have unit length.
