Little Mathematics Library – Method of Successive Approximations

In the Little Mathematics Library we now come to Method of Successive Approximations by N. Ya. Vilenkin. As the title suggests the book has to do with approximation methods, but what kind of approximations and for what kind of use one may ask?

The preface of the book reads:

The main purpose of this book is to present various methods of approximate solution of equations. Their practical value is beyond doubt, but still little attention is paid to them either at school or a college and so someone who has passed a college level higher mathematics course usually has difficulty in solving a transcendental equation of the simplest type. Not only engineers need to solve equations, but also technicians, production technologists and people in other professions as well. It is also good for high-school students to become acquainted with the methods of approximate solution of equations. Since most approximate solution methods involve the idea of the derivative we were forced to introduce this concept. We did this intuitively, making use of a geometric interpretation. Hence, a knowledge of secondary school mathematics will be sufficient for anyone wanting to read this book.

The book was translated from the Russian by Mark Samokhvalov and was first published by Mir in 1979. All credits to the original uploader.
