[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:

$$\int\int\int$$r.e$$^{iqrcos(\theta)}$$sin($$\theta)$$dr.d($$\theta)}$$.d($$\phi)}$$

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

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!
