IDZ 12.3 - Option 8. Decisions Ryabushko AP

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.
2.8. f (x) = sh2x

3. Arrange in a Fourier series in the specified interval periodic function f (x) with period w = 2l
3.8. f (x) = 10 - x, 5 <x <15, l = 5

4. Arrange the Fourier function defined graphically.
 
5. Using the expansion of the function f (x) in a Fourier series in the range, to find the sum of the number series.
