WebEigenvalues are the special set of scalar values that is associated with the set of linear equations most probably in the matrix equations. The eigenvectors are also termed as characteristic roots. It is a non-zero vector that can be changed at most by its scalar factor after the application of linear transformations. WebEigenfunction Expansions The Sturm-Liouville theory provides an in nite sequence of eigenvalue-eigen-function pairs. Among the triumphs of nineteenth-century mathematics was the realization that these sequences of eigenfunctions can be used to represent arbitrary functions1 via in nite series. Thus if fu ng1 n=0 is the
