چکیده
Keyword: Generalized Gregory’s series Trigonometric identities Odd harmonic numbers In this paper the countable family of generalized Gregory’s series (all of which are the power series having the radius of convergence equal to one) is defined. Sums SnðxÞ; n 1⁄4 1;2; . . . of these series are found – first in the definite integral form and next in the form of finite linear combination of arcus tangents of some linear forms of x. It enables to extend the definition of SnðxÞ for all x 2 C n ffiffiffiffiffiffiffi 1 2n p for every n 2 N. Moreover, for new functions SnðxÞ, obtained in result of this extension, many fundamental and surprising integral and trigonometric identities are received. Sums of the series of differences of odd harmonic numbers are presented as well. 2014 Elsevier Inc. All rights reserved.

We do not expect sympathy from a good accountant, or a good lawyer. An unsympathetic accountant or lawyer can be good, we might even take the lack of sympathy to be a mark of professionalism; however, there is something profoundly wrong, even unprofessional, about unsympathetic physicians. Good doctors ought to have a caring heart. We inherit this expectation from the Scottish Enlightenment. Un...
متن کاملUniserial modules of generalized power series
Let R be a ring, M a right R-module and (S,≤) a strictly ordered monoid. In this paper we will show that if (S,≤) is a strictly ordered monoid satisfying the condition that 0 ≤ s for all s ∈ S, then the module [[MS,≤]] of generalized power series is a uniserial right [[RS,≤]] ]]-module if and only if M is a simple right R-module and S is a chain monoid.
متن کاملGeneralized Ritt type and generalized Ritt weak type connected growth properties of entire functions represented by vector valued Dirichlet series
In this paper, we introduce the idea of generalized Ritt type and generalised Ritt weak type of entire functions represented by a vector valued Dirichlet series. Hence, we study some growth properties of two entire functions represented by a vector valued Dirichlet series on the basis of generalized Ritt type and generalised Ritt weak type.
