On the Norms of RFMLR-Circulant Matrices with the Exponential and Trigonometric Functions [PDF]

open access: yesJournal of Mathematics, 2021
In this paper, based on combinatorial methods and the structure of RFMLR-circulant matrices, we study the spectral norms of RFMLR-circulant matrices involving exponential forms and trigonometric functions.

New definitions of exponential, hyperbolic and trigonometric functions on time scales [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2010
We propose two new definitions of the exponential function on time scales. The first definition is based on the Cayley transformation while the second one is a natural extension of exact discretizations.

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 ...

Explicit Properties of Apostol-Type Frobenius–Euler Polynomials Involving q-Trigonometric Functions with Applications in Computer Modeling

open access: yesMathematics, 2023
In this article, we define q-cosine and q-sine Apostol-type Frobenius–Euler polynomials and derive interesting relations. We also obtain new properties by making use of power series expansions of q-trigonometric functions, properties of q-exponential ...

Regularity and wave study of an advection–diffusion–reaction equation [PDF]

open access: yesScientific Reports
In this paper, we investigate the optimal conditions to the boundaries where the unique existence of the solutions to an advection-diffusion-reaction equation is secured by applying the contraction mapping theorem from the study of fixed points. Also, we

Plithogenic functions value [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
The goal of this paper is to find a formula through which we find all the values of the plithogenic functions. we found this formula and proved it, in addition to providing a definition of the exponential, logarithmic, trigonometric plithogenic function.
