1. Arrange the Fourier series of periodic (with period ω = 2π) function f (x) defined on the interval [-π; π]
 
2. Arrange in a Fourier series of f (x), defined in the interval (0; π) continue (where it is defined) its even and odd way. Build charts for each continuing.
2.24. f (x) = shx / 5

3. Arrange in a Fourier series in the specified interval periodic function f (x) with period w = 2l
3.24. f (x) = 1 - | x |, -3
