The totient function appears in many applications of elementary number theory, including Euler's theorem, primitive roots of unity, cyclotomic polynomials, and constructible numbers in geometry. Definition: Euler's summation formula relates the integral of a function over an interval [a, b] with the sum of the function values at the integers in [a, b]. By simple elementary method,we obtain with ease,a highly simple expression for the remainder term of the divisor problem and use it to obtain an Euler-Maclaurin analogue of summation involving divisor function.We also obtain a relation connecting the remainder term of the divisor problem and the remainders of approximate functional equations for Riemann zeta function and its square,for .

Each of the following finite summation formulas holds true: where the empty sum is (as usual) understood to be nil throughout this paper, Setting and in ( 52 ) to ( 53 ) and using some suitable identities in Section 1 , we obtain a set of interesting identities involving binomial coefficients, harmonic numbers, and generalized harmonic numbers given in the following corollary. While it is well-known that the expressions obtained from the Euler-Maclaurin summation formula diverge, our summation formulas are all very rapidly convergent and thus computationally efficient.
