1. Fourier Series Consider a set of eigenfunctionsϕn that are orthogonal, where orthogonality is defined as for m ≠ n An arbitrary function f(x) can be expanded as series of these orthogonal eigenfunctions or Due to orthogonality, we thus know all other ϕnAmϕmintegrate to zero because m ≠ n Thus, the constants in the Fourier series are
