Background: Seasonality of births in Nigeria has been previously addressed in a small number of studies. This study was designed to explore and describe the regional variations in the seasonality of births in Nigeria.Data Source and Methods: A total of 82... see more

In this paper, Fourier series expansions of powers of sine and cosine functions are established for any possible power real or complex or positive integer. Recurrence relations are established to facilities the computations of the coefficients of expansio... see more

We have established sufficient conditions of uniform convergence of the series of the form ?k,l=1ak,lsinkxsinly\sum\limits_{k,l=1} a_{k,l} \sin kx \sin ly in the strip: -8<x<+8-\infty , d?y?2p-d\delta \leqslant y \leqslant 2\pi - \delta (d\delta is ... see more

The work is devoted to the investigation of problem of approximation of continuous periodic functions by trigonometric polynomials, which are generated by linear methods of summation of Fourier series.The simplest example of a linear approximation of peri... see more
