Sum Of Floor Series

At points of discontinuity a fourier series converges to a value that is the average of its limits on the left and the right unlike the floor ceiling and fractional part functions.

Sum of floor series. Int limits 0 infty lfloor x rfloor e x dx. This is an application of the following fun result i published with natalio guersenzvaig a few years ago. At points of continuity the series converges to the true. The other piece in the puzzle is the expression for the sum of an arithmetic sequence which can be found here.

Definite integrals and sums involving the floor function are quite common in problems and applications. Assuming n is even then floor n 2 floor n 1 2. Sum of elements of a geometric progression gp in a given range. Sum of sum series of first n natural numbers sum of series formed by difference between product and sum of n natural numbers program to find sum of series 1 1 2 1 3 1 4.

And floor n 2 2 floor n 2 1. Laguerre based hermite bernoulli polynomials associated with bilateral series ahmad khan waseem araci serkan acikgoz mehmet and esi ayhan tbilisi mathematical journal 2018 airflow and heat transfer in the slot vented room with radiant floor heating unit liu xiang long gong guang cai cheng heng sheng and ding li xing journal of. Summation 8 formulas finite summation 7 formulas infinite summation 1 formula. Sum of product of x and y such that floor n x y.

Summation 8 formulas finite summation 7 formulas infinite summation 1 formula summation 8 formulas floor. For y fixed and x a multiple of y the fourier series given converges to y 2 rather than to x mod y 0. 0 x. Program to print arithmetic progression series.

The best strategy is to break up the interval of integration or summation into pieces on which the floor function is constant.
