# How can I have a bigger integral (\int) delimiter?

I'm writing some integrals and I don't like the way the \int symbol is displayed when it is followed by a big delimiter. Here's the code:

$\int_S\biggl(\nabla\times\bar B - \mu_0\bar J - \mu_0\varepsilon_0\frac{\partial\bar E}{\partial t}\biggr) \cdot\hat n\,ds = 0$


And here's the output:

What I'd like to have is an integral sign taller than the parenthesis, as if it would have a sort of \bigg command right before. Is there any way to do this, or the \int symbol is impossible to modify?

There are a number of integral symbols in various packages. Check out symbols. I don't know if any of them have more than two sizes though. I suspect not. –  TH. Aug 27 '10 at 11:38
