Padé approximants for inverse trigonometric functions and their applications
Journal of Inequalities and Applications, 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

On the Expediency and Possibilities of Approximating a Pure Delay Link
Информатика и автоматизация, 2022 When solving problems of controlling an object with delay, it is often necessary to approximate a pure delay link with a minimum phase link in order to ensure the possibility of using analytical methods for regulator design.

Error estimation in the numerical solution of rational functions
Journal of Applied Sciences and Environmental Management, 2005 In this paper, two methods are described for obtaining estimates of the error of rational functions the Pade\'s and Meahly\'s methods of approximation were used and it was discovered that Maehly\'s proved more accurate than the Pade\'s method.

The VIM-Padé technique for strongly nonlinear oscillators with cubic and harmonic restoring force
Journal of Low Frequency Noise, Vibration and Active Control, 2019 In this paper, we propose an analytical approach (VIM-Padé) based on the variational iteration method (VIM), Laplace transformation and the Padé approximation.

Composed Padé-type approximation
, 2001 We introduce Padé-type (and Padé) approximation to complex-valued harmonic functions in the unit disk D. This coordinate approximation is defined to be a composed Padé-type approximation (respectively, a composed Padé approximation). The basic properties
