Let be d(x-a) the Delta function centered at x=a then could this function be approached by using a Fourier series on the interval (-pi,pi) with -Pi<a<Pi

Anothe question.let be w(x)=sum(1<n<Infinite)d(x-n) then has the function

z(x)=1/w(x) any sense and in teh case w(x)f(x)=g(x) could we do f(x)=g(x)/w(x)?

inf we take instead some of the approximation function to delta for example

sen(nx)/x or nexp(-n^^2x^2)/sqrt(pi) would be the statements above be true?..
