On the trigonometric expansion of elliptic functions [PDF]

open access: goldBulletin of the American Mathematical Society, 1931
The problem of expressing an elliptic function in terms of infinite sums of trigonometric functions has been treated by Hermite, Briot and Bouquet, A. C. Dixon and others. In the present paper we treat the same problem from the point of view of Cauchy's residue theorem in function theory, which is also Briot and Bouquet's starting point, but we differ ...

Padé approximants for inverse trigonometric functions and their applications. [PDF]

open access: yesJ Inequal Appl, 2017
The Padé approximation is a useful method for creating new inequalities and improving certain inequalities. In this paper we use the Padé approximant to give the refinements of some remarkable inequalities involving inverse trigonometric functions, it is

Extended Levett trigonometric series. [PDF]

open access: yesPLoS ONE
An extension of two finite trigonometric series is studied to derive closed form formulae involving the Hurwitz-Lerch zeta function. The trigonometric series involves angles with a geometric series involving the powers of 3.

On the Trigonometric and p-Trigonometric Functions of Elliptical Complex Variables

open access: yesCommunications in Advanced Mathematical Sciences, 2020
In the early 2000s, the geometry of a one-parameter family of generalized complex number systems was studied (Math. Mag. 77(2)(2004)). This family is denoted by Cp.

Critical diapause portion for oscillations: Parametric trigonometric functions and their applications for Hopf bifurcation analyses

open access: yesMathematical Methods in the Applied Sciences, 2019
An important adaptive mechanism for ticks in respond to variable climate is diapause. Incorporating this physiological mechanism into a tick population dynamics model results in a delay differential system with multiple delays.

Approximating trigonometric functions by using exponential inequalities

open access: yesJournal of Inequalities and Applications, 2019
In this paper, some exponential inequalities are derived from the inequalities containing trigonometric functions. Numerical examples show that one can achieve much tighter bounds than those of prevailing methods, which are presented by Cusa, Huygens ...
