- Hi
-
- Can anyone please help me in integrating the following.
-
- infinity
-
- / 4 2 2
- | x sin (Pi a x) sin (Pi b x)
- | ---------------------------- dx
- | 2 2 2 2 2 2
- / (x - d ) (x - c )
-
- -infinity
-
-
- Where a,b,c and d are positive intergers.
-
- This function has double poles on the real axis. Hence theorems
- related to computing such definite integrals dont seem to help me,
- as they allow at the most a simple pole on the real axis. Is there
- some other theorem that I can use? I would appretiate the least bit of
- help on this.
-
- I am begining to think that there is no closed form solution.
- Please help.
-
- Thanks
-
- Amar
