Properties of Trigonometric Functions
Periodic functions are used throughout science to describe oscillations , waves , and other phenomena that exhibit periodicity. Any function that is not periodic is called aperiodic. A function f is said to be periodic if, for some nonzero constant P , it is the case that. A nonzero constant P for which this is the case is called a period of the function.
If there exists a least positive  constant P with this property, it is called the fundamental period also primitive period , basic period , or prime period. Often, "the" period of a function is used to mean its fundamental period. A function with period P will repeat on intervals of length P , and these intervals are sometimes also referred to as periods of the function. Geometrically, a periodic function can be defined as a function whose graph exhibits translational symmetry , i. This definition of periodicity can be extended to other geometric shapes and patterns, as well as be generalized to higher dimensions, such as periodic tessellations of the plane.
A sequence can also be viewed as a function defined on the natural numbers , and for a periodic sequence these notions are defined accordingly. Everyday examples are seen when the variable is time ; for instance the hands of a clock or the phases of the moon show periodic behaviour. Periodic motion is motion in which the position s of the system are expressible as periodic functions, all with the same period.
For a function on the real numbers or on the integers , that means that the entire graph can be formed from copies of one particular portion, repeated at regular intervals. Its period is 1. In particular,.
The subject of Fourier series investigates the idea that an 'arbitrary' periodic function is a sum of trigonometric functions with matching periods. According to the definition above, some exotic functions, for example the Dirichlet function , are also periodic; in the case of Dirichlet function, any nonzero rational number is a period. Using complex variables we have the common period function:. This means that Euler's formula above has the property such that if L is the period of the function, then.
Complex functions may be periodic along one line or axis in the complex plane but not on another. A function whose domain is the complex numbers can have two incommensurate periods without being constant.
The elliptic functions are such functions. Periodic functions can take on values many times. Some periodic functions can be described by Fourier series. For instance, for L 2 functions , Carleson's theorem states that they have a pointwise Lebesgue almost everywhere convergent Fourier series. Fourier series can only be used for periodic functions, or for functions on a bounded compact interval.
Any function that consists only of periodic functions with the same period is also periodic With period equal or smaller. One common subset of periodic functions is that of antiperiodic functions. Thus, a P -antiperiodic function is a 2 P -periodic function. While a P -antiperiodic function is a 2 P -periodic function, the inverse is not necessarily true. A further generalization appears in the context of Bloch's theorems and Floquet theory , which govern the solution of various periodic differential equations.
In this context, the solution in one dimension is typically a function of the form:. Functions of this form are sometimes called Bloch-periodic in this context. In signal processing you encounter the problem, that Fourier series represent periodic functions and that Fourier series satisfy convolution theorems i.
A possible way out is to define a periodic function on a bounded but periodic domain. To this end you can use the notion of a quotient space :. To find the period, T, first find the least common denominator of all the elements in the set. Therefore, the LCD can be seen as a periodicity multiplier. If no least common denominator exists, for instance if one of the above elements were irrational, then the wave would not be periodic.
From Wikipedia, the free encyclopedia. Function that repeats its values at regular intervals or periods. Not to be confused with periodic mapping. It is not to be confused with repeating decimal.

Хейл улыбнулся: - Ну конечно… Принцип Бергофского. - А также здравый смысл! - отрезала. - Кто знает… - Хейл театрально вздохнул.
Она замерла, стараясь успокоиться и чувствуя, как растущая паника сковывает ее тело. Душераздирающий крик, раздавшийся из вентиляционной шахты, все еще звучал в ее ушах. Вопреки отчаянным попыткам подавить охвативший ее страх Сьюзан явственно ощущала, что это чувство завладевает ею безраздельно. Она металась между дверцами кабинок и рукомойниками. Потеряв ориентацию, двигалась, вытянув перед собой руки и пытаясь восстановить в памяти очертания комнаты.
Само ее существование противоречило основным правилам криптографии. Она посмотрела на шефа. - Вы уничтожите этот алгоритм сразу же после того, как мы с ним познакомимся. - Конечно. Так, чтобы не осталось и следа.
Не может быть! - сказала она по-испански. У Беккера застрял комок в горле. Росио была куда смелее своего клиента.
