Integral expression can be added using the
\int_{lower}^{upper}
command.
Note, that integral expression may seems a little different in inline and display math mode - in inline mode the integral symbol and the limits are compressed.
LaTeX code | Output |
---|---|
Integral $\int_{a}^{b} x^2 dx$ inside text |
![]() |
$$\int_{a}^{b} x^2 dx$$ |
![]() |
To obtain double/triple/multiple integrals and cyclic integrals you must use amsmath
and esint
(for cyclic integrals) packages.
Like integral, sum expression can be added using the
\sum_{lower}^{upper}
command.
LaTeX code | Output |
---|---|
Sum $\sum_{n=1}^{\infty} 2^{-n} = 1$ inside text |
![]() |
$$\sum_{n=1}^{\infty} 2^{-n} = 1$$ |
![]() |
In similar way you can obtain expression with product of a sequence of factors using the
\prod_{lower}^{upper}
command.
LaTeX code | Output |
---|---|
Product $\prod_{i=a}^{b} f(i)$ inside text |
![]() |
$$\prod_{i=a}^{b} f(i)$$ |
![]() |
Limit expression can be added using the
\lim_{lower}
command.
LaTeX code | Output |
---|---|
Limit $\lim_{x\to\infty} f(x)$ inside text |
![]() |
$$\lim_{x\to\infty} f(x)$$ |
![]() |
In inline math mode the integral/sum/product lower and upper limits are placed right of integral symbol. Similar is for limit expressions. If you want the limits of an integral/sum/product to be specified above and below the symbol in inline math mode, use the \limits
command before limits specification.
Moreover, adding \displaystyle
beforehand will make the symbol large and easier to read.
On the other hand, \mathlarger
command (provided by relsize
package) is used to get bigger integral symbol in display.
