Web27 aug. 2024 · Find the Fourier cosine expansion of f(x) = x2(3L − 2x) on [0, L]. Solution Here a0 = 1 L∫L 0(3Lx2 − 2x3)dx = 1 L(Lx3 − x4 2) L 0 = L3 2 and an = 2 L∫L 0(3Lx2 − 2x3)cosnπx L dx, n ≥ 1. Evaluating this integral directly is laborious. However, since f ′ (x) = 6Lx − 6x2, we see that f ′ (0) = f ′ (L) = 0. WebQ6.
