Latex Dot Above Variable

You use dot signs in different ways. Sometimes just dot signs are provided, sometimes more than one dot is used and also dot symbols are supplied over and inside the letter.

You watching: Latex dot above variable

In this tutorial, we will talk about detailed the use of all kinds of dot signs and also latex commands.

Simple dot symbol

In latex, the basic dot symbol is stood for by the cdot command. And you might have actually seen its usage in vector dot assets.

Examplecdot → •

documentclassarticleegindocument $$ cdot $$ $$ vecimath cdot vecjmath$$enddocumentOutput :

Also, you deserve to take the assist of physics package. Where the vdot command also is provided to define the vector dot product.

Latex three dots symbol

When you usage n number elements to recurrent a mathematical expression. In that situation, the three-dot symbol is offered without marking each facet in the expression.

Horizontal dotsldots
Horizontal dotscdots
Vertical dotsvdots
Diagonal dotsddots
Inverse Diagonal dotsiddots

Also, tbelow are many type of regulates. In this tutorial, we will only discuss the above five regulates.

1. Horizontal dots on the line

You look at the program listed below. Three dots have been provided together with the ldots command also.

documentclassarticleegindocument $$ a_1, a_2,...,a_n $$ $$ a_1, a_2,ldots,a_n$$enddocumentOutput :

In both situations, tbelow is a distinction between the output. In my opinion, it is much better to use ldots command instead of making use of 3 dots.

2. Horizontal dots above the line

For example, the cdots command is supplied as soon as the sum of n numbers is presented.

documentclassarticleegindocument $$ f(x)=x+ x^2+cdots+x^n $$ enddocumentOutput :

I hope you understand the distinction between ldots and also cdots commands.

3. Vertical dots

Vertical dot consists of three-dot icons, which are located vertically. And this symbol is represented by vdots Command also.

documentclassarticleusepackageamsmathegindocument $$eginbmatrix a_1\ a_2\ vdots\ a_n endbmatrix$$enddocumentOutput :

You have to install the amsmath package when denoting the matrix. And usage the usepackage command also when installing a package.

4. Diagonal dots symbol

This symbol is located along the diagonal from N-W to S-E. And this symbol is mainly offered to reexisting the elements situated along the diagonal of the matrix.

documentclassarticleusepackageamsmathegindocument eginbmatrix a_1 & & \ & ddots & \ & & a_n endbmatrixenddocumentOutput :

If you look at the routine above, you will certainly understand also that ddots has actually been provided for the diagonal dots symbol.

5. Inverse Diagnal dots symbol

The inverse diagonal dots symbol will be located along the S-W to N-E direction. Tright here is even more than one command to represent this symbol but this tutorial will only discuss iddots commands.

documentclassarticleusepackageamsmathusepackagemathdots egindocument $$ eginbmatrix & & a_1\ & ddots & \ a_n & & endbmatrix $$ enddocumentOutput :

To usage the iddots command in Latex you need to install the mathdots package. Since there is no default command in latex to reexisting the inverse diagonal dots symbol.

Latex dot derivative

When a variable is derivative in respect of time, the time derivative is stood for by a dot symbol on the head of that variable.

documentclassarticleegindocument $$fracmathitdrmathitd t=dotr$$ $$fracmathitd^2rmathitd t^2=ddotr$$enddocumentOutput :
