An overview of commonly used math symbols in LaTeX

Since LaTeX offers a large amount of features, it’s hard to lớn remember all commands. Even though commands follow a logical naming scheme, you will probably need a table for the most common math symbols at some point. I don’t want to provide a complete các mục of LaTeX symbols on this website. The ctan already provides a huge menu with currently 5913 symbols, which you can tải về here

*
. Instead I’m trying khổng lồ limit this danh sách to the most common math symbols & commands. If you think I forgot some very important basic function or symbol here, please let me know.

List of common (LaTeX) math symbols

Trigonometric functions

The symbols for trigonometric functions have a very straightforward naming scheme. Just precede the common abbreviations with a backslash & put your variables in braces.

NameSymbolCommand
Sine(sin x)sin x
Cosine(cos x)cos x
Tangent( an x ) an x 
Cotangent(cot x)cot x 
Secant(sec x)sec x 
Cosecant(csc x)csc x

Integrals

LaTeX offers math symbols for various kinds of integrals out of the box. Cảnh báo that you can set the integral boundaries by using the underscore _ và circumflex ^ symbol as seen below.

NameSymbolCommand
Indefinite integral(int f(x) dx)int f(x) dx
Definite integral(int_a^b f(x) x)int_a^b f(x) x
Domain integral(int_D f(x) dx)int_D f(x) dx
Double integral(iint f(x,y) dx dy)iint f(x,y) dx dy
Triple integral(iiint f(x,y,z) dx dy dz)iiint f(x,y,z) dx dy dz
Closed curve integral(oint_C F ds)oint_C F ds

Matrices

Of course LaTeX is able to lớn typeset matrices as well. For this purpose LaTeX offers the following environments. Columns are separated with ampersand và and rows with a double backslash \ (the linebreak command). Make sure that the number of ampersands is the same for every row.

NameSymbolCommand
Matrix(eginmatrix1&0\1&0endmatrix)

eginmatrix1&0\

1&0endmatrix

bMatrix(eginbmatrix1&0\1&0endbmatrix)

eginbmatrix1&0\

1&0endbmatrix

pMatrix(eginpmatrix1&0\1&0endpmatrix)

eginpmatrix1&0\

1&0endpmatrix

vMatrix(eginvmatrix1&0\1&0endvmatrix)

eginvmatrix1&0\

1&0endvmatrix

Determinant(deteginvmatrix1&0\1&0endvmatrix)

deteginvmatrix1&0\

1&0endvmatrix

If you want lớn typeset very large matrices, the following commands can become in handy as well.

Dots

The most common dot symbols used in math notation are available in LaTeX as well.

NameSymbolCommand
Middot / Centered dot(cdot)cdot
Horizontal Dots / Centered dots(cdots)cdots
Vertical Dots(vdots)vdots

Diagonal Dots

(ddots)ddots

Lower Dots

(ldots)

ldots

 

Example: (eginbmatrix1 và 0 & cdots & 0\1 & 0 & cdots & 0\vdots và vdots & ddots & vdots \1 & 0 & 0 và 0endbmatrix)

eginbmatrix

1 & 0 & cdots và 0\

1 & 0 & cdots & 0\

vdots và vdots và ddots & vdots \

1 & 0 & 0 & 0

endbmatrix

Miscellaneous functions

Here are some more basic functions which don’t fit in the categories mentioned above.

NameSymbolCommand
Logarithmic Function / Logarithm(logx)logx
Logarithm (base a)(log_ab)log_ab
Square root function / Square root(sqrtx)sqrtx}
n-th root function / n-th root(sqrtx)sqrtx
Rational function / Fraction(fracu(x)v(x))fracu(x)v(x)
