The aim of this book is to acquaint the reader with the
fundamentals of Lobachevsky's non-Euclidean geometry.
The famous Russian mathematician N. I. Lobachevsky was an
outstanding thinker, to whom is credited one of the greatest
mathematical discoveries, the construction of an original geometric
system distinct from Euclid's geometry. The reader will find
a brief biography of N. I. Lobachevsky in Sec. 1.
Euclidean and Lobachevskian geometries have much in common,
differing only in their definitions, theorems and formulas as
regards the parallel-postulate. To clarify the reasons for these
differences we must consider how the basic geometric concepts
originated and developed, which is done in Sec. 2.
Apart from a knowledge of school plane geometry and
trigonometry reading our pamphlet calls for a knowledge of the
transformation known as inversion, the most important features
of which are reviewed in Sec. 3. We hope that the reader will
be able to grasp its principles with profit to himself and
without great difficulty, since it, and Sec. 10, play very important,
though ancillary, role in our exposition.

Shakhno. Collection of problems in elementary mathematics increased complexity. 2nd ed. 1965.526 pages djvu. 10.3 MB.
Collection contains more than a thousand problems in elementary mathematics, mainly the increased difficulty. Problem, if possible, and provided with a systematic solutions. In some cases, due to the solution of the problem and, where appropriate, are the questions of the theory. Sometimes they are preceded by the decision of the task group, united by a common idea. Clarifications on the theory of equivalence of equations, graphing, complex numbers, inverse trigonometric functions, mathematical induction, and some other issues. The collection is designed for persons who have graduated from high school and want to continue to improve in the problem-solving methods or prepared in high school. It can serve as an additional tool to the teacher in the classroom for individual assignments for students especially interested in mathematics, students of pedagogical institutes.
