Approximations related to the complete p-elliptic integrals

open access: yesOpen Mathematics, 2022
In this paper, the authors present some monotonicity properties for certain functions involving the complete p-elliptic integrals of the first and second kinds, by showing the monotonicity and concavity-convexity properties of certain combinations ...

Efficient estimate of the remainder for the Dirichlet function η(p) for p ∈ R+

open access: yes, 2020
For any k,n,q ∈N, where n≥ 2k+1≥ 3, and p ∈R+ the nth remainder ρ(n, p) of the Dirichlet eta function η(p), known also as the alternating Riemann zeta function, η(p) := ∞ ∑ i=1 (−1)i+1 1 ip , is given in the form ρ(n, p) = ∆q(n, p)+δq(k, p), where k and ...

Very simply explicitly invertible approximations of normal cumulative and normal quantile function

open access: yes, 2014
For the normal cumulative distribution function: Φ(x) we give the new approximation 2**(-22**(1-41**(x/10))) for any x>0, which is very simple (with only integer constants and operations and / and power elevation **) and is very simply explicitly ...

New handy and accurate approximation for the Gaussian integrals with applications to science and engineering

open access: yesOpen Mathematics, 2019
In this work, we propose to approximate the Gaussian integral, the error function and the cumulative distribution function by using the power series extender method (PSEM).

Summation Processes and Gaussian Quadratures

open access: yesSarajevo Journal of Mathematics
In this survey paper we present two classes of summation procedures based on ideas related to Gaussian quadratures. Such summation/integration procedures can be applied to the summation of slowly convergent series.
