1 variation problems
вариационные задачи (конечномерные)
Математические задачи, сводящиеся к поиску наибольших или наименьших значений функций в зависимости от выбора соответствующих аргументов (см. Экстремальные задачи, Экстремум). Решение задачи находится путем дифференцирования функции по аргументу (или аргументам, если их несколько), приравнивания производных нулю и решения полученной системы уравнений. Таким способом решаются многие задачи предельного анализа экономики. Применение В.з. в экономике, в исследовании операций ограничено тем, что: 1) поиск экстремума реально приходится вести не обязательно в точках, где производные обращаются в нуль, а чаще на границе области допустимых решений; 2) нередко применяются функции, для которых производные могут просто не существовать (например, разрывные, кусочно-линейные); 3) само решение системы уравнений, полученной путем дифференцирования основной зависимости, может оказаться не проще, а сложнее, чем поиск экстремума другими методами.

3 listening comprehension
понимание на слухEven in cases where foreign customers can speak English quite well, it is often forgotten that they may not be able to understand it to the required level — bearing in mind the regional and social variation which permeates speech and which can cause major problems of listening comprehension.
