EDUCATION OF A MATHEMATICIAN – EXPERIMENTALIST, OR SOFT MANIFESTO OF EXPERIMENTAL MATHEMATICS

This article is written under the influence of V. I. Arnold’s works, in which he suggested the possibility of considering mathematics as an experimental science, and proved the existence of phenomena in the description of which “soft” models have an advanta...

GENERALIZATION OF SOME TYPES OF INDEFINITE INTEGRALS, WHICH CAN BE SOLVED BY RECURRENCE

In this article we develop a recurrence for the indefinite integrals of the famous type \(\int \tfrac{d x}{\left(a^{2}+x^{2}\right)^{n}}\) and a formula for their calculation. A new methodology and a formula for solving integrals of the type \(I_{k, \alpha}=\...
