There may have been some changes to the final published version and this copy.\n  This is a translation from the Latin original, \"De summis serierum reciprocarum\" (1735). E41 in the Enestrom index. In this paper Euler finds an exact expression for the sum of the squares of the reciprocals of the positive integers, namely pi^2/6. He shows this by applying Newton's identities relating the roots and coefficients of polynomials to the power series of the sine function.
