WebNov 17, 2024 · The Fourier cosine series for the triangle function is therefore given by f(x) = 8 π2(cosx + cos3x 32 + cos5x 52 + ⋯). Convergence of this series is rapid. As an interesting aside, evaluation of this series at x = 0, using f(0) = 1, yields an infinite series for π2 / 8: π2 8 = 1 + 1 32 + 1 52 + ⋯ WebThe Fourier series representation of f(x) is f(x) ∼ a 0 + X∞ n=1 an cos nπx L +bn sin nπx L, where a 0 = 1 2L ZL −L f(x)dx = 1 2L ZL −L xdx+ 1 2L ZL 0 1dx = 1 2L L = 1 2, since the function x is an odd function on [−L,L].
