Residual power series algorithm for fractional cancer tumor models

open access: yesAlexandria Engineering Journal, 2020
In this paper, the new series solutions of some fractional cancer tumor models are investigated by using residual power series method (RPSM). The RPSM is explained with Maclaurin expansion for the solution.

Maclaurin's series expansions of real powers of inverse (hyperbolic) cosine and sine functions with applications [PDF]

open access: yes, 2021
Abstract In the paper, by means of the Faa di Bruno formula, with the help of explicit formulas for special values of the Bell polynomials of the second kind with respect to a specific sequence, and by virtue of two combinatorial identities containing the Stirling numbers of the first kind, the author establishes Maclaurin's series expansions ...

A series expansion of a logarithmic expression and a decreasing property of the ratio of two logarithmic expressions containing cosine

open access: yesOpen Mathematics, 2023
In this study, by virtue of a derivative formula for the ratio of two differentiable functions and with aid of a monotonicity rule, the authors expand a logarithmic expression involving the cosine function into the Maclaurin power series in terms of ...

Method Of Obtaining Approximate Formulas [PDF]

open access: yes, 2018
The two-parameter method of approximating the sum of a power series in terms of its first three terms of the expansion, which allows one to obtain analytic approximations of various functions, decomposes into a Maclaurin series.

Resurgence of the Euler-MacLaurin summation formula [PDF]

open access: yes, 2007
The Euler-MacLaurin summation formula relates a sum of a function to a corresponding integral, with a remainder term. The remainder term has an asymptotic expansion, and for a typical analytic function, it is a divergent (Gevrey-1) series.

Testing Nonlinearity: Decision Rules for Selecting between Logistic and Exponential STAR Models [PDF]

open access: yes, 2001
A new LM specification procedure to choose between Logistic and Exponential Smooth Transition Autoregressive (STAR) models is introduced. The new decision rule has better properties than those previously available in the literature when the model is ...
