I didn't take Eigen Values & Vectors until I took Linear Algebra. In his notes he went over Eigen Values in Diff Eq. Not Vectors, but rather functions. Also I never learned Fourier Series in Diff Eq. We did go over Laplace transformations. Where ever he took this material, they were insanely thorough.
