WebMay 12, 2013 · The coefficients a0, a1,… and b1, b2,… can be found by Functions and Symmetry: It is necessary to classify the functions according to its symmetry properties. Doing so will save computation time and effort. Functions either fall into odd symmetry or even symmetry or no symmetry category. WebTo check, we find the Fourier coefficients manually: Integrate [f [x]*Cos [n*Pi*x], {x, 0, 2}, Assumptions -> Element [n, Integers]] Out [4]= (1 - Cos [n \ [Pi]])/ (n^2 \ [Pi]^2) So Integrate [f [x]*Sin [n*Pi*x], {x, 0, 2}, Assumptions -> Element [n, Integers]] Out [5]= (n \ [Pi] - Sin [n \ [Pi]])/ (n^2 \ [Pi]^2) which is 1/ (n*π).
