The Problems of Mathematical Analysis ... Derivative and Differential” is an indispensable assistant for students, graduate students and anyone who seeks to deepen their knowledge in the field of mathematical analysis. Created by a team of authors, it is a carefully thought out and structured collection of tasks that will help the reader not only to master the theoretical aspects of the derivative and differential, but also to apply this knowledge in practice. The book focuses on key concepts of mathematical analysis, such as the derivative function, the rules of differentiation, the geometric interpretation of the derivative and its application in various fields of science and technology. Each task in this collection is accompanied by detailed solutions and comments, which makes the learning process more accessible and understandable. Readers will be able not only to test their knowledge, but also to understand how to apply the theory in practice, which is especially important for future mathematicians, engineers and physicists. This book will be of interest to senior students of universities and colleges, as well as anyone who is preparing for exams in mathematics or wants to refresh their knowledge. It is suitable for both those who are just starting to study mathematical analysis, and those who already have some experience and want to deepen their skills. If you are looking for literature that will help you to understand complex topics such as limits, continuity and derivatives, then this collection will be a real discovery for you. The topics raised in the book cover a wide range of issues related to derivative and differential. Readers will be able to learn about how the derivative helps in function analysis, how it is used to find extremes, and how the differential allows for an approximate estimate of function changes. This knowledge is fundamental to many scientific disciplines and practical applications, making the book particularly valuable for engineering students. The style of the authors is distinguished by clarity and accessibility of the presentation, which makes it easy to perceive even the most complex concepts. Each section of the book is logically structured, which helps the reader to consistently master the material. In addition, the authors use many examples from real life, which makes the study of mathematical analysis more exciting and practical. The Problems of Mathematical Analysis .
