Especialmente importante entre estas propiedades es el Teorema de Parseval, que establece que la potencia calculada en cualquiera de los dominios es igual a la potencia en el otro In mathematics, Parseval's theorem usually refers to the result that the Fourier transform is unitary; loosely, that the sum (or integral) of the square of a function is equal to the sum (or integral) of the square of its transform Problem Find Pn=(2)2 = 1=4 + 1=+ 1=+ from the known Basel problem formula of P nPand use this to compute the sumn=(2 +1)2 over the odd numbers.
