Fourier series: Convergence of Fourier series
Convergence of Fourier series
Let #f# be the #6#-periodic even function determined by \[f(x)=-4\,x\phantom{xxx}\text{for}\phantom{xxx}0\le x\le3 \] and let \(s(x)\) denote the Fourier series of #f#.
Determine \[s(-18),\hspace{1.1cm}s(-13),\hspace{0.5cm}\text{and}\hspace{0.5cm}s(15)\]
Determine \[s(-18),\hspace{1.1cm}s(-13),\hspace{0.5cm}\text{and}\hspace{0.5cm}s(15)\]
| \(s(-18)=\) |
| \(s(-13)=\) |
| \(s(15)=\) |
