The book "Control works on the sections of higher mathematics: " Integral calculus of functions of one variable" and "Functions of many variables" by O. A. The Federation is an indispensable assistant for students and teachers seeking to better understand and master the complex topics of higher mathematics. This work is a carefully compiled collection of control tasks that will help not only to consolidate theoretical knowledge, but also to develop practical skills in solving problems. In the first part of the book, the author focuses on the integral calculus of functions of a single variable. Here, readers will find a variety of tasks covering basic concepts such as defined and indefinite integrals, methods of integration, and the application of integrals in various fields of science and technology. Each task is accompanied by detailed comments and explanations, which allows students not only to find the right answers, but also to understand how and why certain methods work. This part of the book will be especially useful for those who are preparing for exams or want to improve their skills in solving integral tasks. In the second part, devoted to the functions of many variables, the author offers readers more complex tasks that require a deep understanding of multidimensional analysis. Topics such as partial derivatives, gradients, double and triple integrals, as well as their application in real-world problems are considered here. This part of the book will be a great help for students studying mathematical methods in physics, economics and engineering. The tasks presented in the book will help readers develop analytical thinking and learn how to apply mathematical concepts in practice. The book "Control works on higher mathematics" will be of interest not only to students, but also to teachers who are looking for high-quality materials to test the knowledge of their students. Writing style O. A. The Federation is distinguished by clarity and accessibility, which makes complex mathematical concepts understandable even for beginners. The author skillfully combines theory and practice, which allows readers not only to learn, but also to enjoy the process. The topics raised in the book are of great importance for modern education. In a rapidly developing world, where mathematical knowledge is becoming more and more in demand, the ability to solve problems of higher mathematics opens the door to many career opportunities. The book helps to develop critical thinking and logical skills, which is an important aspect not only in learning, but also in life. For those who are interested in such literature, it is worth paying attention to other works of O. A. Fedenya and his colleagues . “Mathematics books such as
