Fourier series: Convergence of Fourier series
Convergence of Fourier series
Let #f# be the #8#-periodic even function determined by \[f(x)=-3\,x^2\phantom{xxx}\text{for}\phantom{xxx}0\le x\le4 \] and let \(s(x)\) denote the Fourier series of #f#.
Determine \[s(21),\hspace{1.1cm}s(16),\hspace{0.5cm}\text{and}\hspace{0.5cm}s(28)\]
Determine \[s(21),\hspace{1.1cm}s(16),\hspace{0.5cm}\text{and}\hspace{0.5cm}s(28)\]
| \(s(21)=\) |
| \(s(16)=\) |
| \(s(28)=\) |
