“Mathematical Analysis Taskbook (Enhanced Course)” is an indispensable assistant for students, graduate students and anyone who seeks to deepen their knowledge in the field of mathematical analysis. This work, created by a team of authors, is a carefully selected set of tasks that will help readers not only to master the theoretical aspects of the subject, but also to develop practical skills in solving mathematical problems. The book covers a wide range of topics ranging from limit processes and derivatives to integrals and multidimensional analysis. Each chapter contains tasks of varying complexity, which allows the reader to gradually increase the level of complexity and self-confidence. This makes the collection ideal for both beginners and more experienced students who want to refresh their knowledge or prepare for exams. If you study at the Faculty of Mathematics, Physics, Engineering or related specialties, this collection will become your faithful companion in the world of mathematical analysis. It will be especially useful for those who are preparing for test papers or exams, as well as for those who want to prepare for Olympiads and scientific competitions. The questions presented in the book are aimed at developing logical thinking and analytical abilities, which makes it a valuable resource for all who seek a deep understanding of mathematics. The topics raised in the collection cover key concepts of mathematical analysis, such as continuity, differentiation, integrability, and series. Each task is accompanied by detailed solutions and comments, which allows the reader not only to find the right answers, but also to understand how and why they are received. This makes the book not just a collection of tasks, but a real tutorial that will help you master complex concepts and learn how to apply them in practice. The style of the authors is distinguished by clarity and accessibility of presentation, which makes the material understandable even for those who are just starting their way in mathematical analysis. Unlike many other textbooks, where the theoretical part can overshadow the practical, in this collection the emphasis is on solving problems, which allows the reader to immediately apply the knowledge gained. If you are looking for other books on mathematical analysis, pay attention to the "Mathematical Analysis" G. M. Fichtenholtz or "Course of Mathematical Analysis" B. and . Arnold . These works also offer a deep immersion into the subject, but the "Mathematical Analysis Task Collection (Enhanced Course)" stands out for its practical focus and variety of tasks. Do not miss the opportunity to expand your mathematical horizons with this collection. It will become your reliable assistant in mastering mathematical analysis and will help you confidently step on the path to success in studies and scientific activities. This book is not just a set of tasks, but the key to understanding one of the most beautiful and complex sciences, which opens the door to the world of science and technology.
