2.6.2.24 Trigonometric Fourier Series
Condition: decompose an elementary function \ (f (x) \) at a given interval in a row of Fourier: 1) by sinuses; 2) by cosine; 3) get one of the decompositions of a general view; For each case, build graphs of the periodic continuation \ (f (x) \) and the amount of the Fourier series. \ [f (x) = 2 x-4, \ quad x \ in [0, \ pi] \]
