PROPERTIES OF INDEFINITE INTEGRALS, METHODS OF ITS CALCULATION AND, ACCORDINGLY, INTEGRATION OF SOME TRIGONOMETRIC FUNCTIONS

Abstract

Abstract: in this scientific article, we focused on the integral section, which is
one of the important sections of "Higher Mathematics". Here we will consider the
inverse of Differentiation by Integrating. The article shows that the act of
differentiation consists in finding the derivative of a function defined in an area E in
this area or at a point x0 of the area E. Therefore, Integrating consists of finding a
function based on a given derivative, which includes the integral, which is the main
concept of differential equations, and the sample examples for each part are solved in
a sufficiently simple and understandable way.
