# Thread: Notations of Integral

1. ## Notations of Integral

Can Latex shows the notation of integral such as double and triple integral (or just input "\int" for three times?) , line integral and surface integral ?

If it can , how to input

Many thanks !!

Yes. The normal integral is \int. The double integral is \iint, the triple is \iiint, the quadruple integral is \iiiint, etc.

$\displaystyle \int \, \iint \, \iiint \, \iiiint$

3. int /int

Line integral would be $\displaystyle \oint$. Surface integral (from what I've seen) would be $\displaystyle \iint\limits_{\sigma}$.
