Mathematical Analysis For School Students by Lev Pontryagin

About the Book

This book is intended as an introduction to mathematical analysis. It includes material covering all sections of mathematical analysis taught at the secondary school level. The book examines derivatives of polynomials, trigonometric functions, exponential and logarithmic functions. The integral is presented as an operation inverse to differentiation, as the area under a graph, and as the limit of finite sums. At the end of  book, exercises are provided for each section.
The emphasis is placed not on the rigour of exposition, but on computational technique.
For senior school students and for anyone beginning to study mathematical analysis.

    Hello, Damitr! Hope you’re doing well.
    Thanks for taking the time to share this particular book/booklet that you also translated.
    I think you may find the following book by Lev S. Prontryagin (sometimes spelled in English as “Pontrjagin”) useful to share with others as it was part of a series of 4 books he had written for students in school and in university:

    https://link.springer.com/book/10.1007/978-3-642-69040-2

    The other two books (volumes 3 and 4) in the 4-volume series are not translated. The other two are titled “Introduction to Higher Mathematics: Algebra” (vol. 3) and “Introduction to Higher Mathematics: Differential Equations and Their Applications” (vol. 4).
    It seems that this book/booklet you uploaded is a version or synthesis of some kind of the first two volumes of his 4-volume book series called “Learning Higher Mathematics” or “Introduction to Higher Mathematics”.
    The first two volumes (as are shown in the link above) are on the topics of “method of coordinates” and “analysis of the infinitely small”.
    As far as I am aware (based upon cursory searching of the web and library catalogues) volumes 3 and 4 have not been translated from Russian to English. Both volumes exist on Library Genesis and Annas Archive.
