Mathematical Analysis: A Compilation of Individual Tasks . H. 4: A Tutorial” is an indispensable assistant for students, teachers and anyone who seeks to understand deeper the most complex concepts of this fundamental section of mathematics. Created by a team of authors, this tutorial is a unique collection of tasks that not only helps to consolidate theoretical knowledge, but also stimulates analytical thinking, developing the skills of independent solving of complex problems. This part of the series is devoted to the most important aspects of mathematical analysis, such as limits, derivatives, integrals and their applications. The book contains tasks of different levels of complexity, which makes it suitable both for students who are just starting their way in the study of analysis, and for those who are already preparing for exams and test papers. Each task is carefully selected to help the reader not only understand the theory, but also learn how to apply it in practice, solving real mathematical problems encountered in educational institutions and scientific research. A feature of this collection is its interactive approach to learning. The book presents tasks that require not only mechanical memorization of formulas, but also analytical thinking, the ability to logically structure a solution and find non-standard approaches. This format promotes critical thinking and autonomy, which is especially important for those who are preparing to enter higher education or plan to link their professional activities with mathematics, engineering or economics. Mathematical Analysis: A Collection of Individual Tasks . H. 4" is perfect for students of technical and economic specialties, graduate students, teachers and all lovers of mathematics, looking for high-quality material for independent work. Its content is designed for a wide age range - from high school students who are deepening in preparation for the Unified State Exam and OGE, to university students seeking perfection in mastering complex sections of analysis. The author's team, known for its professionalism and pedagogical skills, created a book in a style that combines the rigor of the scientific approach with the accessibility and fun of submitting material. Inspired by classical textbooks on mathematical analysis and modern teaching methods, the authors focused on the practical application of knowledge, which makes the book not just a collection of tasks, but a full-fledged tool for forming a deep understanding of the subject. This part of the series is an excellent choice for those who appreciate a systematic approach and want to prepare for exams or high-level research.
