Здесь приведен вариант доказательства этой формулы. Затем доказывается обобщение формулы Фаа Ди Бруно на случай сложной функции с внутренней функцией 𝑢(𝑥, 𝑦), зависящей от двух независимых переменных. В работе представлена формула для 𝑛-ой производной сложной функции,когда аргументом внешней функции является вектор с произвольным числом компонент (функций от одной переменной). В статье также рассмотрены примеры нахождения производных высших порядков, иллюстрирующие как классическую формулу Фаа Ди Бруно, так и ее обобщения.</p></abstract><trans-abstract xml:lang="en"><p>The focus of the article is the classical Faa Di Bruno formula for computing higher-order derivatives of a complex function 𝐹(𝑢(𝑥)). Here is a version of the proof of this formula. Then we prove a generalization of the Faa Di Bruno formula to the case of a complex function with an inner function 𝑢(𝑥, 𝑦) depending on two independent variables. The paper presents a formula for the 𝑛-th derivative of a complex function, when the argument of the outer function is avector with an arbitrary number of components (functions of one variable). The article also considers examples of finding higher-order derivatives, illustrating both the classical Faa Di Bruno formula and its generalizations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Фаа Ди Бруно</kwd><kwd>𝑛-ая производная сложной функции многих переменных</kwd><kwd>обобщения формулы Фаа Ди Бруно для этих функций</kwd><kwd>формулы бинома и полинома Ньютона.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Faa Di Bruno’s formula</kwd><kwd>𝑛-th derivative of complex functions of several variables</kwd><kwd>generalizations of Faa Di Bruno’s formula for these functions</kwd><kwd>Newton’s binomial and polynomial formulas.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках проекта ФГУ ФНЦ НИИСИ РАН «Развитие методов математического моделирования распределенных систем и соответствующих методов вычисления» FNEF-2022-0007 (Рег. № 1021060909180-7-1.2.1).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Fa´a di Bruno F.
