WebFeb 9, 2024 · 0.2 Derivation of Fourier integral. For seeing how the expansion (3) changes when p →∞ p → ∞ , we put first the expressions (4) of cn c n to the series (3): By denoting ωn:= nπ p ω n := n π p and Δnω:=ωn+1 −ωn = π p Δ n ω := ω n + 1 - ω n = π p , the last equation takes the form. 𝑑 t. WebRemarks on general Fourier series Everything we’ve done with 2ˇ-periodic Fourier series continues to hold in this case, with p replacing ˇ: We can compute general Fourier coe cients by integrating over any \convenient" interval of length 2p. If p is left unspeci ed, then the formulae for a n and b n may involve p. If f(x) is even, then b n ...
