LaTeX How to make an adjusting height integral sign

[Karol]

$$\left \int \frac{dy}{y^{1/3}} \right.$$
Doesn't work.
There also was an examples page in your site, i don't find it

\int is not a delimiter, so it doesn't work with \left. It normally exists in two sizes, depending on whether the equation is displayed or inline. Why do you want to tweak its size?

 

[Karol]

Because there's a fraction inside, but thanks for the answer

 

[Dr Transport]

package bigints or use display style
