Hello,

I've just begun using WA recently and am very fond of it. At the moment I am working on solving an integral and I want to know if WA can help me calculate it - I'm a bit stuck and can't seem to figure out why things aren't working... Many thanks in advance for your input!

Integrate[E^(-2 I \[Pi] t (-(1/6)

Cos[\[Theta]]^2 + (-(5/12) -

1/8 (1 + rinner^2/r^2) Cos[2 \[Phi]] +

3/4 Log[routter/r]) Sin[\[Theta]]^2 +

1/2 (-(1/3) + Cos[\[Theta]]^2 - (

rinner^2 Cos[2 \[Phi]] Sin[\[Theta]]^2)/r^2))), {\[Phi], 0,

2 \[Pi]}]

As you can see, I'd like to take the integral of a complex function. In this step I am taking the integral with respect to phi. There is another integral outside of this with respect to r.

There are some variables here such as theta, rinner, routter, that are not integrated over. Right now when I run this, it just spits out the input. And I can't figure out why...
