[SOLVED] integral with complex numbers

Hi,

I feel really silly for asking this question... but can anyone give me any advice on how to evaluate the following intergral:

[tex]\int\int\int[/tex]r.e[tex]^{iqrcos(\theta)}[/tex]sin([tex]\theta)[/tex]dr.d([tex]\theta)}[/tex].d([tex]\phi)}[/tex]

basically an integral spanning whole of space (I've included the the jacobian r[tex]^{2}[/tex] and sin([tex]\theta)[/tex])

I've tried splitting it into cos(x)+isin(x) but it gets very, very messy:(

Another question:

Is there any way to do braket notation through latex?

nevermind... figured out how to solve it - simple substitution!
