Geometrically, a periodic function can be defined as a function whose graph exhibits translational symmetry, i.e. a function f is periodic with period P if the graph of f is invariant under translation in the x -direction by a distance of P The graph repeats itself after P units. You can think of a period as a repeating interval on a graph: it's the area you can cut and paste over and over again to make a full graph of the function. To put that another way, a graph with period P stays the same if you shift it along the x-axis to the left or right So your function is peridoic with period 2 π. Calling your function for all intends and purposes f (x) = { π − x, 0 ≤ x < π, 0, π ≤ x < 2 π. You can now define f on all of R instead of just on [ 0, 2 π] by setting for y ∈ R the value f (y) = f (y 0), where y 0 = y m o d 2 π, i.e., y 0 ∈ [ 0, 2 π]

Periodic Functions and Fourier Series 1 Periodic Functions A real-valued function f(x) of a real variable is called periodic of period T>0 if f(x+ T) = f(x) for all x2R. For instance the functions sin(x);cos(x) are periodic of period 2ˇ. It is also periodic of period 2nˇ, for any positive integer n. So, there may be in nitely many periods. If needed we may specify the least period as the. Some functions (like Sine and Cosine) repeat forever and are called Periodic Functions. The Period goes from one peak to the next (or from any point to the next matching point): The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2 Plot[periodic[7 + t^2, {t, -5, 5}][x], {x, -40, 40}, Frame -> True] (Note that x was used above for clarity but using t would not conflict.)

Periodic Function (Displacement/Time Graph) Periodic Function Formula. A function f is said to be periodic if, for some non-zero constant P, it is the case that: f (x+P) = f (x) For all values of x in the domain. A non-zero constant P for which this is the case is called a period of the function. Periodic Function Equation .

Section4.3Periodic Functions SubsectionPeriod, Midline and Amplitude All sine and cosine graphs have the characteristic wave shape we've seen in previous examples. But we can alter the size and frequency of the waves by changing the formula for the function The secant and cosecant are both periodic functions with a period of 2π. f(x) = Asec(Bx − C) + D gives a shifted, compressed, and/or stretched secant function graph. See Example 6.2.4 and Example 6.2.5. f(x) = Acsc(Bx − C) + D gives a shifted, compressed, and/or stretched cosecant function graph Periodic and Symmetric Functions. The unit circle has a circumference of C = 2π r = 2π (1) = 2π. Therefore, if a point P travels around the unit circle for a distance of 2π, it ends up where it started. In other words, for any given value q, if 2π is added or subtracted, the coordinates of point P remain unchanged (Figure 1 ) When you graph trigonometric functions, you discover they are periodic; that is, they produce results that repeat predictably. To find the period of a given function, you need some familiarity with each one and how variations in their use affect the period. Once you recognize how they work, you can pick apart trig functions and find the period.

Improve this answer. Follow answered Sep 19. 1. I am inclined to say that the greatest integer function (floor function) is not periodic. Mathworld [1] tells us that, A function f (x) is said to be periodic (or, when emphasizing the presence of a single period instead of multiple periods, singly periodic) with period p if . With the floor function, we can see that for and For example, any periodic processes can be represented as a sum of trigonometric functions (Fourier series). These functions often appear in the solution of differential equations and functional equations. The trigonometric functions include the following \(6\) functions: sine, cosine, tangent, cotangent, secant, and cosecant. For each of these functions, there is an inverse trigonometric.

A periodic function is a function which when has a specific horizontal shift, P, results in a function equal to the original function, i.e., f (x+P) = f (x) f ( x + P) = f ( x) for all values of x within the domain of f. The sine graph repeats itself after 2π, which suggests the function is periodic.
