The Differential Calculus of Functions of Several Variables: A Model Calculation in Higher Mathematics, edited by H. I. Hot and Break is a unique guide that will become an indispensable assistant for students, graduate students and anyone interested in higher mathematics. This publication not only offers a deep dive into the topic, but also makes complex concepts accessible to understanding, which is especially important for those who are faced with mathematics at a higher level. The book focuses on the functions of several variables - one of the key topics in mathematical analysis. The authors consider in detail the basic concepts, such as partial derivatives, gradients, extremums and integrals, which allows the reader not only to master the theory, but also to apply it in practice. Each chapter contains typical tasks and examples, which makes the material more clear and understandable. This is especially useful for students who are preparing for exams or test papers, because practice is an important component of studying higher mathematics. The book will be interesting not only for students of mathematical and engineering specialties, but also for those who work in the field of physics, economics or computer science, where knowledge about the functions of several variables can be applied to real-world problems. The age category of readers varies from high school students preparing for admission to universities, to adults wishing to refresh their knowledge or learn a new discipline. The topics raised in the book cover a wide range of issues, ranging from basics to more complex concepts such as multidimensional integrals and differentiation theorems. This makes the publication valuable not only for study, but also for scientific work, since many of the presented tasks can be used in research projects. The book contributes to the development of logical thinking and analytical skills, which is an important aspect of education in any field. The style of the authors is clear and accessible. They are able to explain complex things in simple language, which makes the material less frightening for beginners.
