Is product of two periodic functions periodic?

Each periodic function has a fundamental frequency, and their product includes both the sum and difference of those fundamental frequencies.

Is the sum of periodic functions always periodic?

Sums of periodic functions are not always periodic , whose terms have least periods 2π and 2 respectively.

Can sum of non periodic functions be periodic?

Yes, it is possible. For example, , satisfy the property. is clearly periodic, and the sum, which is is also periodic.

Can a function have more than one period?

A function of a single complex variable can have two periods, in two different complex directions. Adding either of these periods to the input variable will leave the function unchanged.

Is the sum of two sinusoids always periodic?

Absolutely not. A square wave, for instance is a sum of a series of sinusoids going up to a theoretically infinite frequency.

What is the difference between periodic and non-periodic function?

The basic definition for a periodic function looks fairly straightforward: it repeats its values at set intervals, called periods. This common definition might lead you to think that non-periodic functions are simply those that don’t repeat at set intervals.

Is the derivative of a periodic function periodic?

Sec. 1.5 6 The derivative of a periodic function is periodic.

What is a period of a function?

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. Let’s take a case of an oscillating object, its displacement in periodic motion is represented by a function which is periodic in time;

What is an example of a periodic function?

The movement of planets around the sun, the motion of a yo-yo are all examples of periodic functions. Though the example of a pendulum is a special case of periodic function because it is executing simple harmonic motion, the difference lies in how the motion is expressed mathematically.

How do you find the periodicity of a function?

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.

Does the cosine function repeat itself in time?

We have to concentrate on the elements of this function, the cosine function repeats itself in time from trigonometry we know the following; The movement of planets around the sun, the motion of a yo-yo are all examples of periodic functions.
