A sum is always equal to an integral........

i think i have proved finally that fact..that a series can always be substituted by an integral..

S(0,Infinite)f(n)=I(R)f(x)W(x)dx ..where I(R) means that the integration limits are from -infinite to infinite..and w(x) is a function that is defined as the inverse fourier transform of 1/1-exp(-s).

Hope it can be useful......... if sugerences feel free to post..

Are you familiar with the discrete Fourier transform?
