В книге написанной на основе лекции для студентов, рассказывается о рождении современной математики и теоретической физики в трудах великих ученых XVII века. Некоторые идеи Ньютона и Гюйгенса опередили свое время на несколько столетий и получили развитие только в последние годы. Об этих идеях, включая несколько новых результатов, также расказано в книге.

The standard form of an infinite geometric series is given by An infinite geometric series converges if and only if |r| < 1, otherwise it diverges. The sum of infinite geometric series, for |r| < 1, is given by As stated earlier, some of the proposed methods that will be used in this text give the solution as an infinite geometric series. To determine the exact solution in a closed form, it is normal to find the sum of this series. For this reason we will study examples of infinite geometric series.
This may be clearly seen by considering the equation In this example, λ = 1, |K(x, t)| ≤ 5 and (b − a) = 1; therefore Accordingly, the necessary condition (6) fails to hold, but in fact the integral equation (7) has an exact solution given by and this can be justified through direct substitution. As indicated in our objective for a first course in integral equations, we will pay more attention to the practical techniques for solving integral equations rather than the abstract theorems. In the following we will discuss several methods that handle successfully the Fredholm integral equations of the second kind starting with the most recent methods as indicated earlier.
Notice that it is necessary to verify that the non-canceled terms of u0(x) satisfy the PDE or the integral equation. In case the non-canceled terms of u0(x) did not satisfy the given equation, or the noise terms did not appear, then we proceed to determine more components of the series solution. It was shown by many authors that non homogeneity condition is not sufficient to give noise terms. Moreover, it is necessary that the zeroth component u0(x) should contain the exact solution u(x) among other terms, and this only may give noise terms about components.
