The rectangular coordinate system A system with two number lines at right angles specifying points in a plane using ordered pairs x , y. The horizontal number line is called the x -axis The horizontal number line used as reference in a rectangular coordinate system. These two number lines define a flat surface called a plane The flat surface defined by x - and y -axes. The first number is called the x -coordinate, and the second number is called the y -coordinate. The intersection of the two axes is known as the origin The point where the x - and y -axes cross, denoted by 0, 0.

Function , in mathematics , an expression, rule, or law that defines a relationship between one variable the independent variable and another variable the dependent variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given in by the German mathematician Peter Dirichlet :. If a variable y is so related to a variable x that whenever a numerical value is assigned to x , there is a rule according to which a unique value of y is determined, then y is said to be a function of the independent variable x. In addition to f x , other abbreviated symbols such as g x and P x are often used to represent functions of the independent variable x , especially when the nature of the function is unknown or unspecified.

Эти слова были встречены полным молчанием. Лицо Стратмора из багрового стало пунцовым. Сомнений в том, кого именно обвиняет Чатрукьян, не. Единственный терминал в шифровалке, с которого разрешалось обходить фильтры Сквозь строй, принадлежал Стратмору. Когда коммандер заговорил, в его голосе звучали ледяные нотки: - Мистер Чатрукьян, я не хочу сказать, что вас это не касается, но фильтры обошел.  - Очевидно, что Стратмор с трудом сдерживает гнев.

#### Definition and Properties

Сьюзан сочла его план безукоризненным. Вот он - истинный Стратмор. Он задумал способствовать распространению алгоритма, который АНБ с легкостью взломает. - Полный и всеобщий доступ, - объяснял Стратмор.  - Цифровая крепость сразу же станет всеобщим стандартом шифрования.

В этом случае сотрудники лаборатории систем безопасности тщательно изучали их вручную и, убедившись в их чистоте, запускали в ТРАНСТЕКСТ, минуя фильтры программы Сквозь строй. Компьютерные вирусы столь же разнообразны, как и те, что поражают человека. Подобно своим природным аналогам они преследуют одну цель - внедриться в организм и начать размножаться. В данном случае организмом является ТРАНСТЕКСТ. Чатрукьяна всегда изумляло, что АНБ никогда прежде не сталкивалось с проблемой вирусов.

Он очень о многом ей не сказал - о многих вещах, которых теперь стыдился.
