Please help me to integrate...
This is how far I've gotten...
...not sure what to do...sos...sos...
There are three methods : the first one also the most effective one i suggest is sub. or
so we have
Definitely , it is an integral which is more familiar to you , you can solve it yourself now
The second method is using integration by parts , you can discover how it can work .
The third is the most powerful but it requires much attention :

Oh yes, yes indeed.
Over my head for now, but very interesting. At first I did the integral by substituting euler's relation for the sine function. That made the integral very easy going, but the result was totally useless to me. "i" and me don't get along very well.
Turiski- The magic recipe for integrating has a minus sign where you have a plus sign. It also has the exponential factor 2 down in front of sin(wln(s)). Otherwise looks like you were on target.
Thanks everybody!
