How Many Zeros Are In The Thousands Period

The number in standard form is 308,632,978. Some numbers in word form may not mention a specific period. For example, three million, one hundred twelve written in standard form is 3,000,112. Because the thousands period is not mentioned, you would write three zeros in the thousands period.

Which digit is in the hundred thousands place?

The digit 3 is in the hundred thousands place. Incorrect. The digit 4 is in the hundreds place. The correct answer is three hundred thousands. Incorrect. The number is less than a trillion, so this digit does not exist here. The correct answer is three hundred thousands. Incorrect. The digit 9 is in the hundred millions place.

Definition Of Period In Mathematics

In mathematics, the time interval or gap between two given points is known as a period. This period can be as little as a few microseconds. For instance, the time gap or period between today and tomorrow is one day. There can be variations in the amount or span of time that makes up a period.

In Physics and Maths, the period is generally calculated in terms of time or distance. However, in this article, we will concentrate on the time factor in calculating periods.

Properties Of Periodic Functions

The following properties are helpful for a deeper understanding of the concepts of a periodic function.

• The graph of a periodic function is symmetric and repeats itself along the horizontal axis.
• The domain of the periodic function includes all the real number values, and the range of the periodic function is defined for a fixed interval.
• The period of a periodic function, against which the period repeats itself is equal to the constant across the entire range of the function.
• If f is a periodic function with a period of P, then 1/f will also be a periodic function with the same fundamental period P.
• If f is a periodic function with a period of P, then f is also a periodic function with a period of P/|a|.
• If f is a periodic function with a period of P, then af + b is also a periodic function with a period of P.

Example Question #: Find The Period Of A Sine Or Cosine Function

Please choose the best answer from the following choices.

Find the period of the following function.

Possible Answers:Correct answer:

The period is defined as the length of one wave of the function. In this case, one full wave is 180 degrees or radians. You can figure this out without looking at a graph by dividing with the frequency, which in this case, is 2.

Some Important Periodic Functions

The following are some of the advanced periodic functions, which can be explored further.

Euler’s Formula: The complex number formula eix = Coskx + iSinkx is made up of cosine and sine functions, which are periodic functions. Here these two functions are periodic, and the euler’s formula represents a periodic function and has a period of 2/k.

Jaccobi Elliptic Functions: The graph of these functions is elliptical in shape, rather than a circle, which is often seen for trigonometric functions. These elliptical shapes arise because of the involvement of two variables together, such as the amplitude and speed of a moving body, or the temperature and viscosity of the substance. These functions are commonly used in the description of the motion of a pendulum.

Fourier Series: The Fourier series is a superposition of various periodic wave function series to form a complex periodic function. It is usually composed of sine and cosine functions, and the summation of these wave functions is taken by assigning respective weight components to these series. The Fourier series has applications in the representation of heatwaves, vibration analysis, quantum mechanics, electrical engineering, signal processing, image processing.

What Does A Period In Between Quantifiers Mean

I’m currently reading the notes of an MIT preliminary math course for discrete mathematics.

In section on page 39, some ZFC axioms are written and roughly explained.For example, the “Union” axiom states the following:

$$\forall z. \exists u \forall x. \iff x \in u.$$

And the “Pairing” axiom states the following:

$$\forall x, y. \exists u. \forall z. $$

So the “Union” axiom contains something like $\exists u \forall x$, whereas the “Pairing” axiom has a period between both quantifiers: $\exists u. \forall z.$

So what is the point of the period? As far as I can tell, a period indicates that the statement before it relates to the one after it, that is, $\forall x. \exists y$ means “For all $x$, there exists a $y$.” OTOH, $\forall x \exists y$ simply means “For all $x$ and for some $y$.”

Is that correct? Or what is the meaning of inserting a period?Besides, why is there no $.$ at the end of the “Pairing” axiom?

• $\begingroup$No, it’s not correct. $\forall x\exists y$ means for all $x$ there exists some $y$. The period is purely aesthetic.$\endgroup$ YoTengoUnLCDJun 6, 2016 at 11:41
• $\begingroup$@YoTengoUnLCD OK, but then why not stay consistent? I don’t really see the benefit of the period in terms of readability or whatever.$\endgroup$Jun 6, 2016 at 11:43

The period of each of tan x and cot x = . The period of the wave decreases as its frequency increases. Here is the formula for period of a trigonometric function:
