Complex Number Integral: Tips and Tricks for Solving

[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\intr.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!
