the fourth part of mathematical analysis (Integrals - Differential equations);

The book consists of two chapters. Each chapter contains approximately one hundred solved exercises, the difficulty of which is determined by two or three asterisks. At the end of the book there are general and mixed solved exercises.

  Emphasis is placed on exercises unknown in the Greek literature and on subjects of various exams and competitions (French Baccalaureate , exams of the Universities of Cambridge , London , Oxford , Moscow , Bucharest , etc., G. Putnam competition, Olympiad competitions, E.M.E competitions etc. ) .
