**Determining if a FI period was open or closed on a**

closed as not a real question by Mitch Wheat, Hans Olsson, Jonas, Nathan Fellman, Graviton Nov 11 '10 at 1:04. It's difficult to tell what is being asked here.... 11/06/2008 · A function f is periodic with period P if f(t) = f(t + P) for any choice of t. The general cosine function is periodic with period 2. The function you're working with is periodic, but I leave it to you to figure out the period.

**Show cos(x) is periodic Physics Forums**

What i am trying to do is to write code to extrapolate (following your example) the omega coefficient from a general (not necessarily sine or cosine) trigonometric symbolic function, in order to find the period of the function.... Sine and cosine are periodic functions of period 360°, that is, of period 2π. That’s because sines and cosines are defined in terms of angles, and you can add multiples of 360°, or …

**Can we represent a non-periodic function by a Fourier series?**

29/08/2016 · there are some examples of periodic and a periodic signal with simple word and basic knowledge.... When a function is periodic as the sine function is, it has something called a period. The period of a periodic function is the interval of x -values on which one copy of the repeated pattern occurs.

**Show cos(x) is periodic Physics Forums**

19/09/2010 · The sinousoid signals (sines and cosines) are always periodic. In general, in continuous time, the sum or product of two periodic signals is periodic, so your signal is periodic too.... In each example below we start with a function on defined on an interval, plotted in blue; then we present the periodic extension of this function, plotted in red; then we present the Fourier extension of this function, plotted in green.

## How To Tell If A Function Is Periodic

### Fourier Series of Periodic Functions. A two parts tutorial on Fourier series. In the first part an example is used to show how Fourier coefficients are calculated and in a second part you may use an applet to further explore Fourier series of the same function.

- Periodic Extensions We know that every (suﬃciently smooth) periodic function has a Fourier series expansion. It is fairly common for functions arising from certain applications to be deﬁned only on a …
- The dead giveaway that tells you when Amazon has the best price. This tool looks for lower prices at other stores while you shop on Amazon and tells you where to buy. It is not always easy to check a function is periodic or not. Sometimes you can do it by some tricky way or using some techniques but
- With knowledge of even and odd functions, a zero coefficient may be predicted without performing the integration. Even Functions Recall: A function `y = f(t)` is said to …
- By Mark Wickert . A type of signal classification you need to be able to determine is periodic versus aperiodic. A signal is periodic if x(t) = x(t + T 0), where T 0, the period…
